(5b-3)(b-5)=0

Solution for (5b-3)(b-5)=0 equation:

Simplifying
(5b + -3)(b + -5) = 0

Reorder the terms:
(-3 + 5b)(b + -5) = 0

Reorder the terms:
(-3 + 5b)(-5 + b) = 0

Multiply (-3 + 5b) * (-5 + b)
(-3(-5 + b) + 5b * (-5 + b)) = 0
((-5 * -3 + b * -3) + 5b * (-5 + b)) = 0
((15 + -3b) + 5b * (-5 + b)) = 0
(15 + -3b + (-5 * 5b + b * 5b)) = 0
(15 + -3b + (-25b + 5b2)) = 0

Combine like terms: -3b + -25b = -28b
(15 + -28b + 5b2) = 0

Solving
15 + -28b + 5b2 = 0
