    \[\frac{2}{-49 - \sqrt{2409}} , \frac 14 (49+ \sqrt{2409})\]

    Can you show me the steps so I can compare them with mine?

    m^2-49/2m-1/2=0, so a=1 b=49/2 c=-1/2, to be used in the quadratic formula of -b+- square root of b^2-4ac/2a.

    b = -49/2 And then \[\frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\]

    m^2-49/2m=1/2 (m-49/4)^2-(49/4)^2=1/2 This should be the first step

    @andras, I get m^2-49/2m+2401/16, the 2401/16 in the rules for completing a square is take the coefficient of the second term divide by 2, then square it and add it to the end as the third term and also add it to the other side. So, 1/2 x 49/2= 49/4 ^2=2401/16. This is what I came up with after doing that (m^2-49/4)^2=2409/16?
