Question

(14ac)-a^2-2ac+b^2)
I need to subtract by removing a factor of 1 when possible
the answer that I got is
-a^2+16ac+b^2
can anyone tell me if this is right and if not can you help me solve

Answer 1

You wrote : (14ac)-a^2-2ac+b^2)

I noticed that you have one right bracket but two left brackets, so that indicates a typo error. (Syntax error in "old computer programming" language)
You probably meant:
(14ac) - (a^2-2ac+b^2)
= 14ac - a^2 + 2ac - b^2
= 16ac - a^2 - b^2

You almost had that, except for the -b^2
