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


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

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

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

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

Combine like terms: -3b + 4b = 1b
b(-12 + 1b + b2) = 0
(-12 * b + 1b * b + b2 * b) = 0
(-12b + 1b2 + b3) = 0

Solving
-12b + 1b2 + b3 = 0

Solving for variable 'b'.
