Solve by factoring: x^2-8x+20=0

no real solution

Step-by-step explanation:

x2−8x+20=0

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

1x2+−8x+20=0

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

x=

−b±√b2−4ac

2a

x=

−(−8)±√(−8)2−4(1)(20)

2(1)

x=

8±√−16

2

No real solutions.

If you meant x^2+ 8x- 20=0, then the answers are 10 or 2.
