Question

solution set for quadratic equation (x+9)^2=-25

Answer 1

Distributing out, it becomes x^2+18x+106 = 0

Answer 2

Using the quadratic formula, we obtain:

x= -9 (+/-) 5 i, where i is sqrt(1)

Answer 3

The roots are complex.

Answer 4

take square root of both sides
x+9=plus or minus sqrt{-25}
x=-9 plus or minus sqrt{-25}
x=-9 plus or minus 5i
x=-9+5i or x=-9-5i
