Solution for y=(x-7)x(x-7)x(x-7) equation: 


Simplifying
y = (x + -7) * x(x + -7) * x(x + -7)

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

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

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

Reorder the terms for easier multiplication:
y = x * x(-7 + x)(-7 + x)(-7 + x)

Multiply x * x
y = x2(-7 + x)(-7 + x)(-7 + x)

Multiply (-7 + x) * (-7 + x)
y = x2(-7(-7 + x) + x(-7 + x))(-7 + x)
y = x2((-7 * -7 + x * -7) + x(-7 + x))(-7 + x)
y = x2((49 + -7x) + x(-7 + x))(-7 + x)
y = x2(49 + -7x + (-7 * x + x * x))(-7 + x)
y = x2(49 + -7x + (-7x + x2))(-7 + x)

Combine like terms: -7x + -7x = -14x
y = x2(49 + -14x + x2)(-7 + x)

Multiply (49 + -14x + x2) * (-7 + x)
y = x2(49(-7 + x) + -14x * (-7 + x) + x2(-7 + x))
y = x2((-7 * 49 + x * 49) + -14x * (-7 + x) + x2(-7 + x))
y = x2((-343 + 49x) + -14x * (-7 + x) + x2(-7 + x))
y = x2(-343 + 49x + (-7 * -14x + x * -14x) + x2(-7 + x))
y = x2(-343 + 49x + (98x + -14x2) + x2(-7 + x))
y = x2(-343 + 49x + 98x + -14x2 + (-7 * x2 + x * x2))
y = x2(-343 + 49x + 98x + -14x2 + (-7x2 + x3))

Combine like terms: 49x + 98x = 147x
y = x2(-343 + 147x + -14x2 + -7x2 + x3)

Combine like terms: -14x2 + -7x2 = -21x2
y = x2(-343 + 147x + -21x2 + x3)
y = (-343 * x2 + 147x * x2 + -21x2 * x2 + x3 * x2)
y = (-343x2 + 147x3 + -21x4 + x5)

Solving
y = -343x2 + 147x3 + -21x4 + x5

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Simplifying
y = -343x2 + 147x3 + -21x4 + x5
