Factor completely 8x^5 + 2x^4 + 4x^2.
Prime
2(4x5 + x4 + 2x2)
2x(4x4 + x3 + 2x)
2x2(4x3 + x2 + 2)

Answer 1

C. 2x^2(4x^3 + x^2 + 2)

Answer 2

Find the Greatest Common Factor (GCF)

GCF = 2x^2

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

2x^2(8x^5/2x^2 + 2x^4/2x^2 + 4x^2/2x^2)

Simplify each term in parenthesis

= C. 2x^2(4x^3 + x^2 + 2)
