Question

Factor the expression.

4x + 8

The factored expression is

Answer 1

Find the Greatest Common Factor (GCF)

GCF = 4

Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

4(ax/4 + 8/4)

Simplify each term in parenthesis

4(x + 2)

Answer 2

4(x + 2)

Explanation:

Factor out common factors from each term. Note the factors for each number

4: 1, 2, 4

8: 1, 2, 4, 8

The largest factor for each is 4, and so divide 4 from both terms.

(4x + 8)/4 = (x + 2)

4(x + 2) is your factored expression.
