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

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

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

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

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

Multiply (6 + y) * (4 + y)
(6(4 + y) + y(4 + y)) = 0
((4 * 6 + y * 6) + y(4 + y)) = 0
((24 + 6y) + y(4 + y)) = 0
(24 + 6y + (4 * y + y * y)) = 0
(24 + 6y + (4y + y2)) = 0

Combine like terms: 6y + 4y = 10y
(24 + 10y + y2) = 0

Solving
24 + 10y + y2 = 0

Solving for variable 'y'.

0 + y = 0 + -6
y = 0 + -6

Combine like terms: 0 + -6 = -6
y = -6

Simplifying
y = -6
Subproblem 2
Set the factor '(4 + y)' equal to zero and attempt to solve:

Simplifying
4 + y = 0

Solving
4 + y = 0

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

Add '-4' to each side of the equation.
4 + -4 + y = 0 + -4

Combine like terms: 4 + -4 = 0
0 + y = 0 + -4
y = 0 + -4

Combine like terms: 0 + -4 = -4
y = -4

Simplifying
y = -4
Solution
y = {-6, -4}
