answer these correctly. don't just say "i don't know", "look it up" or anything of the like. if you do, a moderator will deal with you accordingly and you will lose points.

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.

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

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
C <<<<<<
Try and figure out what's wrong with D

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

Is there a picture because i cannot answer it sorry
