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


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

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

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

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

Multiply (4 + b) * (-2 + b)
(4(-2 + b) + b(-2 + b))(1 + b) = 0
((-2 * 4 + b * 4) + b(-2 + b))(1 + b) = 0
((-8 + 4b) + b(-2 + b))(1 + b) = 0
(-8 + 4b + (-2 * b + b * b))(1 + b) = 0
(-8 + 4b + (-2b + b2))(1 + b) = 0

Combine like terms: 4b + -2b = 2b
(-8 + 2b + b2)(1 + b) = 0

Multiply (-8 + 2b + b2) * (1 + b)
(-8(1 + b) + 2b * (1 + b) + b2(1 + b)) = 0
((1 * -8 + b * -8) + 2b * (1 + b) + b2(1 + b)) = 0
((-8 + -8b) + 2b * (1 + b) + b2(1 + b)) = 0
(-8 + -8b + (1 * 2b + b * 2b) + b2(1 + b)) = 0
(-8 + -8b + (2b + 2b2) + b2(1 + b)) = 0
(-8 + -8b + 2b + 2b2 + (1 * b2 + b * b2)) = 0
(-8 + -8b + 2b + 2b2 + (1b2 + b3)) = 0

Combine like terms: -8b + 2b = -6b
(-8 + -6b + 2b2 + 1b2 + b3) = 0

Combine like terms: 2b2 + 1b2 = 3b2
(-8 + -6b + 3b2 + b3) = 0

Solving
-8 + -6b + 3b2 + b3 = 0
