Solution for y=-2(9-x)(-x+3) equation:


Simplifying
y = -2(9 + -1x)(-1x + 3)

Reorder the terms:
y = -2(9 + -1x)(3 + -1x)

Multiply (9 + -1x) * (3 + -1x)
y = -2(9(3 + -1x) + -1x * (3 + -1x))
y = -2((3 * 9 + -1x * 9) + -1x * (3 + -1x))
y = -2((27 + -9x) + -1x * (3 + -1x))
y = -2(27 + -9x + (3 * -1x + -1x * -1x))
y = -2(27 + -9x + (-3x + 1x2))

Combine like terms: -9x + -3x = -12x
y = -2(27 + -12x + 1x2)
y = (27 * -2 + -12x * -2 + 1x2 * -2)
y = (-54 + 24x + -2x2)
