Solution for 2(b-3)(b-8)=0 equation:


Simplifying
2(b + -3)(b + -8) = 0

Reorder the terms:
2(-3 + b)(b + -8) = 0

Reorder the terms:
2(-3 + b)(-8 + b) = 0

Multiply (-3 + b) * (-8 + b)
2(-3(-8 + b) + b(-8 + b)) = 0
2((-8 * -3 + b * -3) + b(-8 + b)) = 0
2((24 + -3b) + b(-8 + b)) = 0
2(24 + -3b + (-8 * b + b * b)) = 0
2(24 + -3b + (-8b + b2)) = 0

Combine like terms: -3b + -8b = -11b
2(24 + -11b + b2) = 0
(24 * 2 + -11b * 2 + b2 * 2) = 0
(48 + -22b + 2b2) = 0

Solving
48 + -22b + 2b2 = 0
