8) factor 6+17g+10g^2
10g^2+17g+6
(5g+6)(2g+1)
C is the answer.

9) which one is a perfect square?
4x^2-14x+49 doesn't factor
4x^2-28x+49=(2x-7)(2x-7)
x^2-x+1 doesn't factor
x^2-2x+2 doesn't factor
B is the answer.

11) factor y^2-2y-48
(y+6)(y-8)
D is the answer

12) for the last one you can multiply the answers out of factor.

Sorry this took forever. It's hard to use the website cuz I'm used to the app.


Best wishes!

I wonder if google really will give answers to questions like this. Just typing out loud.

A square has the form of 2 identical expressions. Try B first.
4x^2 - 28x + 49
(2x - 7)(2x - 7) and that is looking good. They are the same and when you expand them, they give what you started with.

10
You can eliminate A where does the - come from?
You should try D before you look at B or C
(x + 1/2) (x + 1/2)
x^2 + 1/2x + 1/2x + 1/4
x^2 + x + 1/4
x^2 + x + 0.25 <<<<==== Answer D

8
You can eliminate A. There's no minus anywhere but in the 2 factors. The original question should have a minus before the 17 if it is to be chosen.

B is incorrect. The middle term would be 32 if it was the right answer.

C We better do this one carefully. Using Foil we get
6*1 + 12g + 5g + 10g^2
6 + 17g + 10g^2
Answer: C <<<<<< =====
Try and figure out what's wrong with D

11
The answer is B <<<<<===== See if you can get this on your own.
