Question

check for GCF and factor completely, I dont know how to do this :((
1. 2x^3 - 2x^2 +3x - 3
2. 4x^2 + 4x + 1
3. 14x^2 + 49xy + 21y^2

Answer 1

2. (2x+1)^2
3. 7(2x+y)(x+3y)

Answer 2

first one you want to group your first 2 terms and last 2 terms (as tutordiffeq will show)
the second one you can factor pretty simple. and the last you have to use pascal's triangle

Answer 3

#1 will be 2x^2(x-1)+3(x-1)
(2x^2+3)(x-1)

Answer 4

thanks
