Answer 2

Answer:

there is no real number solution

Step-by-step explanation:

Given

x² + 6x = - 10

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(3)x + 9 = - 10 + 9

(x + 3)² = - 1 ( take the square root of both sides )

x + 3 = ± $\sqrt{-1}$

there is no real number whose square is - 1
