Question

what are the roots to the following coordinates?
-4x^2-28x-48=0

Answer 1

divide all factors by -4, then factor and solve

Answer 2

Dividing out -4 and you get \[x^2+7x+12\]
factoring this gives you \[(x+3)(x+4)\] which means that the roots are -3 and -4

Answer 3

"to the following coordinates"- I don't get that last part of your question. You must of copied something wrong or that I must of skipped some kind of naming session in maths.
