Answer:

x = −3 and x = −2

Step-by-step explanation:

x^2 + 5x = −6

Add 6 to each side

x^2 + 5x+6 = −6+6

x^2 +5x+6 =0

Factor

What 2 number multiply to 6 and add to 5

3*2 =6

3+2 =5

(x+3)(x+2) =0

Using the zero product property

x+3 =0             x+2 =0

x+3-3=0-3         x+2-2=0-2

x=-3                       x=-2
