Let’s solve the problem step by step.
We are given the expression:
6x² + 18x⁵
We need to factor out the GCF (Greatest Common Factor) using the 3 steps shown in the worksheet.
---
STEP 1: Find the GCF of all terms
The two terms are:
- 6x²
- 18x⁵
First, find the GCF of the coefficients: 6 and 18.
Factors of 6: 1, 2, 3, 6
Factors of 18: 1, 2, 3, 6, 9, 18
→ The greatest common factor is
6
Now for the variables: x² and x⁵
When finding GCF of variables with exponents, take the variable with the
smallest exponent.
So, GCF of x² and x⁵ is
x²
Therefore, the overall GCF is:
6x²
✔ Step 1 Answer: GCF = 6x²
---
STEP 2: Divide all terms by the GCF
Divide each term by 6x²:
First term: 6x² ÷ 6x² =
1
Second term: 18x⁵ 6x² = (18÷6) × (x⁵÷x²) =
3x³
✔ Step 2 Answer: Remainder inside parentheses will be (1 + 3x³)
---
STEP 3: Put the GCF outside parenthesis and the remainder inside parenthesis
So we write:
6x²(1 + 3x³)
*Check by distributing:*
6x² × 1 = 6x²
6x² × 3x³ = 18x⁵
→ 6x² + 18x⁵ → matches original!

Final Answer:
6x²(1 + 3x³)
