(4y+6)(1+y)=0

Solution for (4y+6)(1+y)=0 equation:

Simplifying
(4y + 6)(1 + y) = 0

Reorder the terms:
(6 + 4y)(1 + y) = 0

Multiply (6 + 4y) * (1 + y)
(6(1 + y) + 4y * (1 + y)) = 0
((1 * 6 + y * 6) + 4y * (1 + y)) = 0
((6 + 6y) + 4y * (1 + y)) = 0
(6 + 6y + (1 * 4y + y * 4y)) = 0
(6 + 6y + (4y + 4y2)) = 0

Combine like terms: 6y + 4y = 10y
(6 + 10y + 4y2) = 0

Solving
6 + 10y + 4y2 = 0

Solving for variable 'y'.

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

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

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

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

Simplifying
y = -1
Solution
y = {-1.5, -1}
