Solution for y(y+5)+2y(y-2)= equation:


Simplifying
y(y + 5) + 2y(y + -2) = 0

Reorder the terms:
y(5 + y) + 2y(y + -2) = 0
(5 * y + y * y) + 2y(y + -2) = 0
(5y + y2) + 2y(y + -2) = 0

Reorder the terms:
5y + y2 + 2y(-2 + y) = 0
5y + y2 + (-2 * 2y + y * 2y) = 0
5y + y2 + (-4y + 2y2) = 0

Reorder the terms:
5y + -4y + y2 + 2y2 = 0

Combine like terms: 5y + -4y = 1y
1y + y2 + 2y2 = 0

Combine like terms: y2 + 2y2 = 3y2
