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


Simplifying
0 = x3(y + 4) + y(y + 4)

Reorder the terms:
0 = x3(4 + y) + y(y + 4)
0 = (4 * x3 + y * x3) + y(y + 4)
0 = (4x3 + x3y) + y(y + 4)

Reorder the terms:
0 = 4x3 + x3y + y(4 + y)
0 = 4x3 + x3y + (4 * y + y * y)
0 = 4x3 + x3y + (4y + y2)

Solving
0 = 4x3 + x3y + 4y + y2

Solving for variable 'x'.

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

Add '-4x3' to each side of the equation.
0 + -4x3 = 4x3 + x3y + 4y + -4x3 + y2
Remove the zero:
-4x3 = 4x3 + x3y + 4y + -4x3 + y2

Reorder the terms:
-4x3 = 4x3 + -4x3 + x3y + 4y + y2

Combine like terms: 4x3 + -4x3 = 0
-4x3 = 0 + x3y + 4y + y2
-4x3 = x3y + 4y + y2

Add '-1x3y' to each side of the equation.
-4x3 + -1x3y = x3y + 4y + -1x3y + y2

Reorder the terms:
-4x3 + -1x3y = x3y + -1x3y + 4y + y2

Combine like terms: x3y + -1x3y = 0
-4x3 + -1x3y = 0 + 4y + y2
-4x3 + -1x3y = 4y + y2

Reorder the terms:
-4x3 + -1x3y + -4y + -1y2 = 4y + -4y + y2 + -1y2

Combine like terms: 4y + -4y = 0
-4x3 + -1x3y + -4y + -1y2 = 0 + y2 + -1y2
-4x3 + -1x3y + -4y + -1y2 = y2 + -1y2

Combine like terms: y2 + -1y2 = 0
-4x3 + -1x3y + -4y + -1y2 = 0

Factor out the Greatest Common Factor (GCF), '-1'.
-1(4x3 + x3y + 4y + y2) = 0

Ignore the factor -1.
