Solve by completing the square with working out

-6x-x^2-8

x = -3 +/- sqrt(17)

Step-by-step explanation:

-6x - (x^2) - 8 = 0

-((x^2) + 6x + 8) = 0

(x^2) + 6x + 8 = 0

(x + 3)^2 - 1 = 0

(x + 3)^2 = 1

x + 3 = +/- sqrt(1)

x + 3 = +/- 1

x = -3 +/- 1

x = -4, -2

the answer would be c:   ax + b = ax + c

step-by-step explanation:

a)(x-2)^2+(y-1)^2=9
