Solution for y=3*(x+5)*(x+7) equation: 


Simplifying
y = 3(x + 5)(x + 7)

Reorder the terms:
y = 3(5 + x)(x + 7)

Reorder the terms:
y = 3(5 + x)(7 + x)

Multiply (5 + x) * (7 + x)
y = 3(5(7 + x) + x(7 + x))
y = 3((7 * 5 + x * 5) + x(7 + x))
y = 3((35 + 5x) + x(7 + x))
y = 3(35 + 5x + (7 * x + x * x))
y = 3(35 + 5x + (7x + x2))

Combine like terms: 5x + 7x = 12x
y = 3(35 + 12x + x2)
y = (35 * 3 + 12x * 3 + x2 * 3)
y = (105 + 36x + 3x2)

Solving
y = 105 + 36x + 3x2

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Simplifying
y = 105 + 36x + 3x2
