Question

True or false: The quadratic formula is =
True
-b± √b-4(a) (c)
———————
2(a)

Answer 1

False, everything is correct except for the b in the square root. It should be (b)^2

Answer 2

False.

Explanation:

The quadratic formula is as follows:


`-b + \sqrt{(b^2-4ac)/(2a)` or
`-b - \sqrt{(b^2-4ac)/(2a)` (I wasn't able to do the plus/minus so that's why there's two equations since you get two different answers from doing plus or minus)

The incorrect portion would be the variable "b" under the square root, as the correct format would be b².
