Question

solve x^2+4x+4=-28

Answer 1

easiest way to ,solve it is to factorise on the left hand side.

the solve for x.

You'll end up with 2 complex roots to the question...

Answer 2

There's a few ways to solve...i'll show you how to complete the square...
You have to first get the constant to one side.
x^2+4x=-32
Then you take the coefficient of 4 and divide by 2. then square that;
x^2+4x+4=-28
(x+2)^2=-28

Answer 3

wait...did you need x?

Answer 4

the alternative is to add 28 to both sides and use the general quadratic formula...

but again, you'll end up with 2 complex roots

Answer 5

it says solve using any method

Answer 6

I came up with x^2+4x+28=0

Answer 7

Good, now use the quadratic formula, completing the square, or factor!!
