I wonder if google really will give answers to questions like this. Just typing out loud.
9 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.
