Solution for y=(3x^2+4)(4x-5) equation: 


Simplifying
y = (3x2 + 4)(4x + -5)

Reorder the terms:
y = (4 + 3x2)(4x + -5)

Reorder the terms:
y = (4 + 3x2)(-5 + 4x)

Multiply (4 + 3x2) * (-5 + 4x)
y = (4(-5 + 4x) + 3x2 * (-5 + 4x))
y = ((-5 * 4 + 4x * 4) + 3x2 * (-5 + 4x))
y = ((-20 + 16x) + 3x2 * (-5 + 4x))
y = (-20 + 16x + (-5 * 3x2 + 4x * 3x2))
y = (-20 + 16x + (-15x2 + 12x3))
y = (-20 + 16x + -15x2 + 12x3)

Solving
y = -20 + 16x + -15x2 + 12x3
