kaswanson · Answer

I'm familiar with the quadratic equation, but I wasn't sure if there was another way to solve it, or how I would even get it into the form to use the quadratic equation.

Your "-1/2(m-2)(m+1)+5=0" would be clearer if you were to enclose that fraction, -1/2, inside parentheses:  (-1/2)(m-2)(m+1)+5=0.

First, multiply both sides of this equation by -2 to clear it of fractions.
Second, multiply out the two polynomials on the left side.
Third, combine all like terms (e. g., -2+5=3).

$-0.5(m-2)(m+1)+5 = 0\
-0.5(m^2+m-2m-2)+5=0\
-0.5m^2+0.5m+1+5=0\
-0.5m^2+0.5m + 6 = 0$\
