Answer:
Step-by-step explanation:
r²+8r=−7
Step 1: Subtract -7 from both sides.
r²+8r−(−7)=−7−(−7)
r²+8r+7=0
Step 2: Use quadratic formula with a=1, b=8, c=7.
r=![r=\frac{-b+or-\sqrt{-4ac} }{2a}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B-b%2Bor-%5Csqrt%7B-4ac%7D%20%20%7D%7B2a%7D)
![r=\frac{-8+or-\sqrt{(8})^2-4(1)(7) }{2(1)}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B-8%2Bor-%5Csqrt%7B%288%7D%29%5E2-4%281%29%287%29%20%7D%7B2%281%29%7D)
