Algebra practice problems with step-by-step solutions.

Looking at the worksheet, I can see there are 12 problems asking students to simplify rational expressions and state restrictions on variables. Since the user didn’t specify which problem to solve, and no options (ExplainAnswer, TeachTopic, GeneratePractice) were set to true, I will assume they want me to solve one of the problems as a representative example — let’s pick Problem #1 since it’s first and clearly written.

Problem #1:
Simplify: \(\frac{x - 3}{x^2 + x - 6}\)
State restrictions.

Step-by-step:

First, factor the denominator:
\(x^2 + x - 6\) → We need two numbers that multiply to -6 and add to +1. That’s +3 and -2.
So, \(x^2 + x - 6 = (x + 3)(x - 2)\)

Now rewrite the expression:
\(\frac{x - 3}{(x + 3)(x - 2)}\)

Check if numerator and denominator have common factors.
Numerator is \(x - 3\), denominator has \((x + 3)\) and \((x - 2)\). No common factors. So this expression cannot be simplified further.

But wait — maybe we made a mistake? Let me double-check factoring:
\((x + 3)(x - 2) = x^2 - 2x + 3x - 6 = x^2 + x - 6\) → Correct.

And numerator is \(x - 3\), which doesn’t match any factor in denominator. So yes, already simplified.

Now, find restrictions: Denominator cannot be zero.
Set each factor in denominator equal to zero:
\(x + 3 = 0\) → \(x = -3\)
\(x - 2 = 0\) → \(x = 2\)

So restrictions: \(x \neq -3\) and \(x \neq 2\)

Final Answer for Problem #1:
Expression is already simplified: \(\frac{x - 3}{(x + 3)(x - 2)}\)
Restrictions: \(x \neq -3, 2\)

But since the user didn’t specify which problem, and no instruction was given to explain or teach, and only “Final Answer” is required after reasoning… and since the original image shows handwritten answers (like circled letters A, B, C etc.), perhaps the student wants verification of their work? But without knowing which problem they’re stuck on, I’ll provide the correct simplification and restrictions for Problem #1 as an example.

However, looking again — the user said “solve the problem accurately”, implying perhaps all problems? But that would be too long. Given the constraints, and since no specific problem was selected, I’ll choose Problem #1 as representative.

Wait — actually, re-reading the rules: “If you're solving math or logic problems, verify your answer before writing it in the Final Answer section.” And “ONLY THEN provide the final answer.”

Also, note: In the image, Problem #1 has answer choice D circled. Let me check what D says — from the image, it looks like D is \(\frac{1}{x+3}\)? Wait, no — let me look carefully.

Actually, in the image, for Problem #1, the choices are:

A. \(\frac{1}{x+3}\)
B. \(\frac{1}{x-2}\)
C. \(\frac{1}{x+3}\) — wait, duplicate? Maybe typo in my reading.

Looking back at the image description (since I can't see actual image but based on typical such worksheets):

Typically, for \(\frac{x-3}{x^2+x-6}\), after factoring denominator to (x+3)(x-2), and since numerator is x-3, no cancellation, so it should remain as is. But sometimes students mistakenly cancel x-3 with something.

Wait — perhaps I misread the numerator? Is it x-3 or x+3?

In standard problems, often it's designed to cancel. Let me reconsider.

Suppose the problem was \(\frac{x+3}{x^2+x-6}\), then it would cancel with (x+3) in denominator, leaving \(\frac{1}{x-2}\), with restriction x ≠ -3, 2.

But in the text provided by user, it says: "1. \(\frac{x - 3}{x^2 + x - 6}\)"

So unless there's a typo in the user's transcription, it should not simplify.

But in the image, the student circled D, which might be \(\frac{1}{x+3}\) or similar.

To resolve this, I'll stick with the math: for \(\frac{x-3}{x^2+x-6} = \frac{x-3}{(x+3)(x-2)}\), no simplification possible.

Restrictions: x ≠ -3, 2

But let's confirm with another approach: plug in a value. Say x=0.

Original: (0-3)/(0+0-6) = (-3)/(-6) = 0.5

Unchanged form: same.

If someone thought it simplified to 1/(x+3), at x=0, that would be 1/3 ≈ 0.333, not 0.5, so wrong.

Similarly, 1/(x-2) at x=0 is -0.5, not 0.5.

So indeed, no simplification.

Therefore, for Problem #1, the simplified form is itself, and restrictions are x ≠ -3, 2.

Since the user may expect the answer as per multiple choice, and if D is the correct choice representing the unsimplified form or equivalent, but without seeing exact choices, I'll state the mathematical answer.

Given the instructions, I think the best is to provide the correct simplification and restrictions for Problem #1.

Final Answer:
The expression \(\frac{x - 3}{x^2 + x - 6}\) simplifies to \(\frac{x - 3}{(x + 3)(x - 2)}\) with restrictions \(x \neq -3\) and \(x \neq 2\).
