y = -2(x + -9)(x + -7)

Reorder the terms:
y = -2(-9 + x)(x + -7)

Reorder the terms:
y = -2(-9 + x)(-7 + x)

Multiply (-9 + x) * (-7 + x)
y = -2(-9(-7 + x) + x(-7 + x))
y = -2((-7 * -9 + x * -9) + x(-7 + x))
y = -2((63 + -9x) + x(-7 + x))
y = -2(63 + -9x + (-7 * x + x * x))
y = -2(63 + -9x + (-7x + x2))

Combine like terms: -9x + -7x = -16x
y = -2(63 + -16x + x2)
y = (63 * -2 + -16x * -2 + x2 * -2)
y = (-126 + 32x + -2x2)
