Solution for y=5(2x-1)(x-4) equation:


Simplifying
y = 5(2x + -1)(x + -4)

Reorder the terms:
y = 5(-1 + 2x)(x + -4)

Reorder the terms:
y = 5(-1 + 2x)(-4 + x)

Multiply (-1 + 2x) * (-4 + x)
y = 5(-1(-4 + x) + 2x * (-4 + x))
y = 5((-4 * -1 + x * -1) + 2x * (-4 + x))
y = 5((4 + -1x) + 2x * (-4 + x))
y = 5(4 + -1x + (-4 * 2x + x * 2x))
y = 5(4 + -1x + (-8x + 2x2))

Combine like terms: -1x + -8x = -9x
y = 5(4 + -9x + 2x2)
y = (4 * 5 + -9x * 5 + 2x2 * 5)
y = (20 + -45x + 10x2)

Solving
y = 20 + -45x + 10x2
