Answer:
x = 0 or x = -8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
17=x2+8x+17
Step 2: Subtract x^2+8x+17 from both sides.
17−(x2+8x+17)=x2+8x+17−(x2+8x+17)
−x2−8x=0
Step 3: Factor left side of the equation.
(−x)(x+8)=0
Step 4: Set factors equal to 0.
−x=0 or x+8=0
x=0 or x=−8
