    okay and you already know the quadratic formula. \(x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\)

    \[\frac{ -6 \pm \sqrt{6^2 - 20} }{ 2}\] This would be a simpler form of the formula given the terms. I just eliminated the a = 1 and added the -4(5).

    yep. now square the 6 under the radical

    I'm sure you know what \(6^2\)is right?

    The problem being, when I solve, I get 4.75 and -1.25, which if you look at the answers above, these are not it.

    okay, first off, how did you get 3.5?

    \(6^2=36\) so you would take \(\large\sqrt{36-20}\). What is 36-20?

    \[\frac{ -6 \pm \sqrt{36 - 20}}{ 2} = \frac{ -6 \pm \sqrt{12} }{ 2 }\] \[\sqrt{12} = 3.5\]

    36-20 does not equal 12. double check your math there

    you forgot something. \(\large\sqrt{16}=?\)

    because you have \(\LARGE \frac{-6\pm\sqrt{16}}{2}\)

    right. Even if you take 4 \[\frac{ -6 \pm 4 }{ 2 } = -2/2 = -1 \space or -5\]
