Question

What are the solutions of the quadratic equation X2+11x=-28

Answer 1

X² + 11x = -28
to find the solution of this polynomial, it'll be easiest to try and factor it. the first thing you need to do is move everything to one side:

x² + 11x = -28 ... add 28
x² + 11x + 28 = 0 ... factor
(x + 7)(x + 4) = 0 ... now set both of your factors equal to zero and solve for x

x + 7 = 0
x = -7

x + 4 = 0
x = -4

Answer 2

Answer:

-3, -8
