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

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

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

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

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

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

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

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

Solving for variable 'm'.
