4y^3(3y+4)(y-5)=

Solution for 4y^3(3y+4)(y-5)= equation:

Simplifying
4y3(3y + 4)(y + -5) = 0

Reorder the terms:
4y3(4 + 3y)(y + -5) = 0

Reorder the terms:
4y3(4 + 3y)(-5 + y) = 0

Multiply (4 + 3y) * (-5 + y)
4y3(4(-5 + y) + 3y * (-5 + y)) = 0
4y3((-5 * 4 + y * 4) + 3y * (-5 + y)) = 0
4y3((-20 + 4y) + 3y * (-5 + y)) = 0
4y3(-20 + 4y + (-5 * 3y + y * 3y)) = 0
4y3(-20 + 4y + (-15y + 3y2)) = 0

Combine like terms: 4y + -15y = -11y
4y3(-20 + -11y + 3y2) = 0
(-20 * 4y3 + -11y * 4y3 + 3y2 * 4y3) = 0
(-80y3 + -44y4 + 12y5) = 0

Solving
-80y3 + -44y4 + 12y5 = 0

Solving for variable 'y'.

Add '-5' to each side of the equation.
5 + -5 + -1y = 0 + -5

Combine like terms: 5 + -5 = 0
0 + -1y = 0 + -5
-1y = 0 + -5

Combine like terms: 0 + -5 = -5
-1y = -5

Divide each side by '-1'.
y = 5

Simplifying
y = 5
Solution
y = {-1.333333333, 5}
