    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.

    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}
