(m^2-9)-(m-3)=

Solution for (m^2-9)-(m-3)= equation:

Simplifying
(m2 + -9) + -1(m + -3) = 0

Reorder the terms:
(-9 + m2) + -1(m + -3) = 0

Remove parenthesis around (-9 + m2)
-9 + m2 + -1(m + -3) = 0

Reorder the terms:
-9 + m2 + -1(-3 + m) = 0
-9 + m2 + (-3 * -1 + m * -1) = 0
-9 + m2 + (3 + -1m) = 0

Reorder the terms:
-9 + 3 + -1m + m2 = 0

Combine like terms: -9 + 3 = -6
-6 + -1m + m2 = 0

Solving
-6 + -1m + m2 = 0

Solving for variable 'm'.
