    Hey maybe it will factor (m+8)(m-3)=0 Thats easier than a quadratic solution set is m=3 and m=-8

    I've got to run. On the quadratic equations, first see if it factors if not then go to the quadratic formula.

    When you have been instructed to solve by a certain method such as "completing the squares. Using proper algebraic operations get the equation into this form: Ax^2 + Bx = C Divide thru by A to get X^2 + B/A x=C/A Add (B/A)^2 to both sides; .......will get back with you later, gotta run
