Question

Solve the equation by graphing. - x2 = 8x + 20

Answer 1

Answer: No real solutions.

Step-by-step explanation: −x2=8x+20

Step 1: Subtract8x+20 from both sides.

−x2−(8x+20)=8x+20−(8x+20)

−x2−8x−20=0

For this equation: a=-1, b=-8, c=-20

−1x2+−8x+−20=0

Step 2: Use quadratic formula with a=-1, b=-8, c=-20
