Question

Solve the equation using quadratic formula -x^2+27=6x

Answer 1

D) x = -9, x = 3 I believe. :D

Answer 2

x=3 or x=−9

Explanation:

Step 1: Subtract 6x from both sides.

−x^2+27−6x=6x−6x

−x^2−6x+27=0

Step 2: Factor left side of equation.

(−x+3)(x+9)=0

Step 3: Set factors equal to 0.

−x+3=0 or x+9=0

x=3 or x=−9
