Question 77306: ok i messed up on the other question i sent you guys.. I have one more for you to check.. if you would! THANK you SOOO MUCH!!
Use the quadratic form of completing the square to find the vertex of...
f(x) = 2x^2 -4x + 5
Factor out 2.. f (x) = 2(x^2-2x + 5/2)
2(x^2-2x + 1 -1 + 5/2
2(x^2 - 2x + 1 + 3/2)
2([x-1]^2 + 3/2)
f(x) = 2(x-1)^2 +3
Vertex: (1,3)

Question 77360: This is in the factoring chapter. When I apply the distributive property, than combine like terms, I'm not getting the right answer.
a(b-4) -c(b-4)
a*b= ab, a*-4=4a
-c*b=-cb, -c*-4=4c now it's ab-4a-cb+4c and took out the parenthsis
I don't really have any like terms, so wouldn't this be the answer?
The book says the answer is (b-4)(a-c). I can't get to this.
And the instuctions for this section say "factor each polynomial completely"
So am I suppose to factor?
Thanks...I hope this make sense to you, cuz it isn't to me.
