Answer:
x=-2,10
Step-by-step explanation:
You weren't very clear on what you wanted, and there are way easier ways to solve this but:
Quadratic formula is x = ( -b ± √( b^2 - 4ac ) ) / ( 2a ) where a=x^2 or 1, b=-8, and c=-20.
When you input these values into the equation and solve, you get x=20/2 and x=-4/2. When you solve both of these, you get x=-2 and x=10.
Please mark as brainliest ;)
