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


Simplifying
y = 3(x + -2)(x + -5)

Reorder the terms:
y = 3(-2 + x)(x + -5)

Reorder the terms:
y = 3(-2 + x)(-5 + x)

Multiply (-2 + x) * (-5 + x)
y = 3(-2(-5 + x) + x(-5 + x))
y = 3((-5 * -2 + x * -2) + x(-5 + x))
y = 3((10 + -2x) + x(-5 + x))
y = 3(10 + -2x + (-5 * x + x * x))
y = 3(10 + -2x + (-5x + x2))

Combine like terms: -2x + -5x = -7x
y = 3(10 + -7x + x2)
y = (10 * 3 + -7x * 3 + x2 * 3)
y = (30 + -21x + 3x2)
