Question

Solve the following equation using the quadratic formula

Answer 1

A

Explanation:

The quadratic formula is
`x=(-b+/-√(b^2-4ac) )/(2a)`. Here a=1, b=-8, and c=97.

Substitute and you'll have:

`x=(-b+/-√(b^2-4ac) )/(2a) =(8+/-√(-8^2-4(1)(97)) )/(2(1))=(8+/-√(64-388) )/(2))`

`(8+/-√(-324) )/(2)=(8+/-18i )/(2)=4+/- 9i`
