# Math Help - Solving an Equation

1. ## Solving an Equation

Simply solve:

fg(x) = 3x^(2)-6x+17

Last question on me stoopid Maths paper. Can't really think of what to do.

Silly me. I think I know how to do it now.

Thanks.

Solve for what

If $fg(x)=0$ use the quadratic formula

Hi StephenPoco,

I'm not sure what fg(x) is, but I would set the expression = 0 and use the quadratic formula to solve.

$3x^2-6x+17=0$

$x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}$
