Algebra practice problems covering simplification, multiplication, and solving of algebraic expressions and equations.

It seems you've uploaded an image containing a math worksheet with problems related to algebraic expressions. Since the image itself isn't directly visible in this context, I'll provide a general explanation of how to approach each type of problem typically found in such worksheets. If you can describe or transcribe specific problems from the worksheet, I can solve them step by step.

General Approach to Solving Problems in Algebra

#### 1. Simplifying Expressions
- Combine like terms: Group terms with the same variable and exponent.
- Factor out common factors: Use the distributive property to simplify.
- Apply exponent rules: For example:
- $ x^a \cdot x^b = x^{a+b} $
- $ \frac{x^a}{x^b} = x^{a-b} $
- $ (x^a)^b = x^{a \cdot b} $

#### 2. Multiplying Expressions
- Distribute terms: Use the distributive property.
- Multiply coefficients and variables separately.
- Simplify using exponent rules.

#### 3. Dividing Expressions
- Cancel common factors: Simplify fractions by canceling out common terms in the numerator and denominator.
- Use exponent rules for division: $ \frac{x^a}{x^b} = x^{a-b} $.

#### 4. Performing Operations and Simplifying
- Follow the order of operations (PEMDAS/BODMAS): Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
- Simplify step by step.

Example Problems and Solutions

#### Problem Type 1: Simplify the Expression
Example Problem: Simplify $ 3x^2 + 5x - 2x^2 + 7x $.

Solution:
1. Combine like terms:
- For $ x^2 $ terms: $ 3x^2 - 2x^2 = x^2 $.
- For $ x $ terms: $ 5x + 7x = 12x $.
2. Write the simplified expression:
$$
x^2 + 12x
$$

#### Problem Type 2: Multiply Expressions
Example Problem: Simplify $ (2x^3)(3x^2) $.

Solution:
1. Multiply the coefficients: $ 2 \cdot 3 = 6 $.
2. Add the exponents of $ x $: $ x^3 \cdot x^2 = x^{3+2} = x^5 $.
3. Write the simplified expression:
$$
6x^5
$$

#### Problem Type 3: Divide Expressions
Example Problem: Simplify $ \frac{12x^5}{4x^2} $.

Solution:
1. Divide the coefficients: $ \frac{12}{4} = 3 $.
2. Subtract the exponents of $ x $: $ x^5 \div x^2 = x^{5-2} = x^3 $.
3. Write the simplified expression:
$$
3x^3
$$

#### Problem Type 4: Perform Operations and Simplify
Example Problem: Simplify $ (x^2 + 3x - 2) + (2x^2 - 5x + 4) $.

Solution:
1. Combine like terms:
- For $ x^2 $ terms: $ x^2 + 2x^2 = 3x^2 $.
- For $ x $ terms: $ 3x - 5x = -2x $.
- For constant terms: $ -2 + 4 = 2 $.
2. Write the simplified expression:
$$
3x^2 - 2x + 2
$$
