Question

Which of the following is a solution of x² + 14x + 112 = 0? If necessary, round to the nearest hundredth.
A.x = –0.24
B.x = –4.24
C.4.24
D.no solution
I think it is D...?

Answer 1

completing the square is very quick here

x² + 14x + 112 = 0
x² + 14x + 49 = -112 +49
(x + 7)^2 = - 63
x+7 = ± √-63 , which is not a real number.

so, you are correct!
