Solution for Y+Y(2Y-20)(2Y-20)=720 equation: 


Simplifying
Y + Y(2Y + -20)(2Y + -20) = 720

Reorder the terms:
Y + Y(-20 + 2Y)(2Y + -20) = 720

Reorder the terms:
Y + Y(-20 + 2Y)(-20 + 2Y) = 720

Multiply (-20 + 2Y) * (-20 + 2Y)
Y + Y(-20(-20 + 2Y) + 2Y * (-20 + 2Y)) = 720
Y + Y((-20 * -20 + 2Y * -20) + 2Y * (-20 + 2Y)) = 720
Y + Y((400 + -40Y) + 2Y * (-20 + 2Y)) = 720
Y + Y(400 + -40Y + (-20 * 2Y + 2Y * 2Y)) = 720
Y + Y(400 + -40Y + (-40Y + 4Y2)) = 720

Combine like terms: -40Y + -40Y = -80Y
Y + Y(400 + -80Y + 4Y2) = 720
Y + (400 * Y + -80Y * Y + 4Y2 * Y) = 720
Y + (400Y + -80Y2 + 4Y3) = 720

Combine like terms: Y + 400Y = 401Y
401Y + -80Y2 + 4Y3 = 720

Solving
401Y + -80Y2 + 4Y3 = 720

Solving for variable 'Y'.

Reorder the terms:
-720 + 401Y + -80Y2 + 4Y3 = 720 + -720

Combine like terms: 720 + -720 = 0
-720 + 401Y + -80Y2 + 4Y3 = 0

The solution to this equation could not be determined.
