Solution for =(y+6u)(7y-7u-5) equation: 


Simplifying
0 = (y + 6u)(7y + -7u + -5)

Reorder the terms:
0 = (6u + y)(7y + -7u + -5)

Reorder the terms:
0 = (6u + y)(-5 + -7u + 7y)

Multiply (6u + y) * (-5 + -7u + 7y)
0 = (6u * (-5 + -7u + 7y) + y(-5 + -7u + 7y))
0 = ((-5 * 6u + -7u * 6u + 7y * 6u) + y(-5 + -7u + 7y))

Reorder the terms:
0 = ((-30u + 42uy + -42u2) + y(-5 + -7u + 7y))
0 = ((-30u + 42uy + -42u2) + y(-5 + -7u + 7y))
0 = (-30u + 42uy + -42u2 + (-5 * y + -7u * y + 7y * y))

Reorder the terms:
0 = (-30u + 42uy + -42u2 + (-7uy + -5y + 7y2))
0 = (-30u + 42uy + -42u2 + (-7uy + -5y + 7y2))
