Question 125207: Hello: I am studying for the clep exam for college level algebra. this is a problem in the clep study guide..it gives the problem and the answer, but not the steps. I am not sure of the steps, could you show me the steps taken to arrive at the answer? thank You
(2x-1)^2= 4x^2-4x+1
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
(2x-1)^2
The process is called FOIL
(2x-1)(2x-1)
F means 1st & 1st
(2x)*(2x) = 4x^2
O means outer & outer
(2x)*(-1) = -2x
I means inner * inner
(-1)(2x) = -2x
L means last *last
(-1)*(-1) = 1
-------------------
After you do that, you combine the terms to get:
4x^2 -4x + 1
