Solution for (a-1)(b+2)= equation:


Simplifying
(a + -1)(b + 2) = 0

Reorder the terms:
(-1 + a)(b + 2) = 0

Reorder the terms:
(-1 + a)(2 + b) = 0

Multiply (-1 + a) * (2 + b)
(-1(2 + b) + a(2 + b)) = 0
((2 * -1 + b * -1) + a(2 + b)) = 0
((-2 + -1b) + a(2 + b)) = 0
(-2 + -1b + (2 * a + b * a)) = 0
(-2 + -1b + (2a + ab)) = 0

Reorder the terms:
(-2 + 2a + ab + -1b) = 0
(-2 + 2a + ab + -1b) = 0

Solving
-2 + 2a + ab + -1b = 0

Solving for variable 'a'.
