(4m-1)(m+2)=

Solution for (4m-1)(m+2)= equation:

Simplifying
(4m + -1)(m + 2) = 0

Reorder the terms:
(-1 + 4m)(m + 2) = 0

Reorder the terms:
(-1 + 4m)(2 + m) = 0

Multiply (-1 + 4m) * (2 + m)
(-1(2 + m) + 4m * (2 + m)) = 0
((2 * -1 + m * -1) + 4m * (2 + m)) = 0
((-2 + -1m) + 4m * (2 + m)) = 0
(-2 + -1m + (2 * 4m + m * 4m)) = 0
(-2 + -1m + (8m + 4m2)) = 0

Combine like terms: -1m + 8m = 7m
(-2 + 7m + 4m2) = 0

Solving
-2 + 7m + 4m2 = 0

Solving for variable 'm'.
