y = -3(x + -2)(x + -7)

Reorder the terms:
y = -3(-2 + x)(x + -7)

Reorder the terms:
y = -3(-2 + x)(-7 + x)

Multiply (-2 + x) * (-7 + x)
y = -3(-2(-7 + x) + x(-7 + x))
y = -3((-7 * -2 + x * -2) + x(-7 + x))
y = -3((14 + -2x) + x(-7 + x))
y = -3(14 + -2x + (-7 * x + x * x))
y = -3(14 + -2x + (-7x + x2))

Combine like terms: -2x + -7x = -9x
y = -3(14 + -9x + x2)
y = (14 * -3 + -9x * -3 + x2 * -3)
y = (-42 + 27x + -3x2)
