Question

Determine the root of the equation by factoring 3x^2-x-4=0.

I have both of the roots solved, but when I verify it does not come out to a zero. Why is this?

Answer 1

The roots you found should be
`(3x-4)(x+1)=0`, which shows that
`x = (4)/(3) \\ x=-1`

Explanation:

You likely messed up when trying to one or both of the roots back into the equation.
