Solution for (2m+5)(m-3)= equation:


Simplifying
(2m + 5)(m + -3) = 0

Reorder the terms:
(5 + 2m)(m + -3) = 0

Reorder the terms:
(5 + 2m)(-3 + m) = 0

Multiply (5 + 2m) * (-3 + m)
(5(-3 + m) + 2m * (-3 + m)) = 0
((-3 * 5 + m * 5) + 2m * (-3 + m)) = 0
((-15 + 5m) + 2m * (-3 + m)) = 0
(-15 + 5m + (-3 * 2m + m * 2m)) = 0
(-15 + 5m + (-6m + 2m2)) = 0

Combine like terms: 5m + -6m = -1m
(-15 + -1m + 2m2) = 0

Solving
-15 + -1m + 2m2 = 0
