(2b-3)(b-4)=0

Solution for (2b-3)(b-4)=0 equation:

Simplifying
(2b + -3)(b + -4) = 0

Reorder the terms:
(-3 + 2b)(b + -4) = 0

Reorder the terms:
(-3 + 2b)(-4 + b) = 0

Multiply (-3 + 2b) * (-4 + b)
(-3(-4 + b) + 2b * (-4 + b)) = 0
((-4 * -3 + b * -3) + 2b * (-4 + b)) = 0
((12 + -3b) + 2b * (-4 + b)) = 0
(12 + -3b + (-4 * 2b + b * 2b)) = 0
(12 + -3b + (-8b + 2b2)) = 0

Combine like terms: -3b + -8b = -11b
(12 + -11b + 2b2) = 0

Solving
12 + -11b + 2b2 = 0

Solving for variable 'b'.
