Question

Solve the following equation using the quadratic formula

Answer 1

Answer:

A

Step-by-step explanation:

The quadratic formula is $x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}$. Here a=1, b=-8, and c=97.

Substitute and you'll have:

$x=\frac{-b+/-\sqrt{b^2-4ac} }{2a} =\frac{8+/-\sqrt{-8^2-4(1)(97)} }{2(1)}=\frac{8+/-\sqrt{64-388} }{2)}$

$\frac{8+/-\sqrt{-324} }{2}=\frac{8+/-18i }{2}=4+/- 9i$
