Question

X^2+8x-20 use quadratic formula to solve for x

Answer 1

Answer:

2 and -10

Step-by-step explanation:

formula = $\frac{-8+0r-\sqrt{8^{2}-4(1)(-20) } }{2(1)}$

--solve

$\frac{-8+-\sqrt{64+80} }{2}$

$\frac{-8+or-\sqrt{144} }{2}$

$\frac{-8+or-12}{2}$

divide by two

-4±6

-4+6=2

-4-6=-10
