Question

Factor the expression.

5x + 15

The factored expression is

Answer 1

Find the Greatest Common Factor (GCF)

GCF = 5

Factor out the GCF (Write the GCF first, and then in parenthesis, divide each term by the GCF.)

5(5x/5 + 15/5)

Simplify each term in parenthesis

5(x + 3)

Answer 2

5(x + 3)

Explanation:

Hello!

To factor, take out the greatest common factor, or the largest factor in each term.

The factors of 5x are 5 and x.

The factors of 15 are 3 and 5.

The greatest common factor is 5, so take it out of the expression.

• 5x + 15
• 5(x) + 5(3)
• 5(x + 3)

The factored expression is 5(x + 3).
