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


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

Reorder the terms:
a = 3a(5 + 2b)(a + -2b)

Multiply (5 + 2b) * (a + -2b)
a = 3a(5(a + -2b) + 2b * (a + -2b))
a = 3a((a * 5 + -2b * 5) + 2b * (a + -2b))
a = 3a((5a + -10b) + 2b * (a + -2b))
a = 3a(5a + -10b + (a * 2b + -2b * 2b))
a = 3a(5a + -10b + (2ab + -4b2))

Reorder the terms:
a = 3a(5a + 2ab + -10b + -4b2)
a = 3a(5a + 2ab + -10b + -4b2)
a = (5a * 3a + 2ab * 3a + -10b * 3a + -4b2 * 3a)

Reorder the terms:
a = (-30ab + -12ab2 + 15a2 + 6a2b)
a = (-30ab + -12ab2 + 15a2 + 6a2b)

Solving
a = -30ab + -12ab2 + 15a2 + 6a2b

Solving for variable 'a'.

Reorder the terms:
a + 30ab + 12ab2 + -15a2 + -6a2b = -30ab + 30ab + -12ab2 + 12ab2 + 15a2 + -15a2 + 6a2b + -6a2b

Combine like terms: -30ab + 30ab = 0
a + 30ab + 12ab2 + -15a2 + -6a2b = 0 + -12ab2 + 12ab2 + 15a2 + -15a2 + 6a2b + -6a2b
a + 30ab + 12ab2 + -15a2 + -6a2b = -12ab2 + 12ab2 + 15a2 + -15a2 + 6a2b + -6a2b

Combine like terms: -12ab2 + 12ab2 = 0
a + 30ab + 12ab2 + -15a2 + -6a2b = 0 + 15a2 + -15a2 + 6a2b + -6a2b
a + 30ab + 12ab2 + -15a2 + -6a2b = 15a2 + -15a2 + 6a2b + -6a2b

Combine like terms: 15a2 + -15a2 = 0
a + 30ab + 12ab2 + -15a2 + -6a2b = 0 + 6a2b + -6a2b
a + 30ab + 12ab2 + -15a2 + -6a2b = 6a2b + -6a2b

Combine like terms: 6a2b + -6a2b = 0
a + 30ab + 12ab2 + -15a2 + -6a2b = 0
