Question

Check for the GCF then factor completely by grouping 2x^3 +4x^2 +10x + 20

Answer 1

gcf = 2

factor by grouping
= 2x^2(x + 2) + 10(x+ 2)
= (2x^2 + 10)(x+2)
= 2(x^2 + 5)(x+ 2)

Answer 2

oh thanks :) do you do x^3 - 2x^2 + 4^x - 8 the same way??

Answer 3

yes factor out x^2 for ist two terms
then then 4x for second 2

Answer 4

so it would be (x-2) (x^2 + 4) ?
