Solution for (3a+b)(3a-b)(2a+5b)= equation: 


Simplifying
(3a + b)(3a + -1b)(2a + 5b) = 0

Multiply (3a + b) * (3a + -1b)
(3a * (3a + -1b) + b(3a + -1b))(2a + 5b) = 0
((3a * 3a + -1b * 3a) + b(3a + -1b))(2a + 5b) = 0

Reorder the terms:
((-3ab + 9a2) + b(3a + -1b))(2a + 5b) = 0
((-3ab + 9a2) + b(3a + -1b))(2a + 5b) = 0
(-3ab + 9a2 + (3a * b + -1b * b))(2a + 5b) = 0
(-3ab + 9a2 + (3ab + -1b2))(2a + 5b) = 0

Reorder the terms:
(-3ab + 3ab + 9a2 + -1b2)(2a + 5b) = 0

Combine like terms: -3ab + 3ab = 0
(0 + 9a2 + -1b2)(2a + 5b) = 0
(9a2 + -1b2)(2a + 5b) = 0

Multiply (9a2 + -1b2) * (2a + 5b)
(9a2 * (2a + 5b) + -1b2 * (2a + 5b)) = 0
((2a * 9a2 + 5b * 9a2) + -1b2 * (2a + 5b)) = 0
