(y-3)(4y+2)=

Solution for (y-3)(4y+2)= equation:

Simplifying
(y + -3)(4y + 2) = 0

Reorder the terms:
(-3 + y)(4y + 2) = 0

Reorder the terms:
(-3 + y)(2 + 4y) = 0

Multiply (-3 + y) * (2 + 4y)
(-3(2 + 4y) + y(2 + 4y)) = 0
((2 * -3 + 4y * -3) + y(2 + 4y)) = 0
((-6 + -12y) + y(2 + 4y)) = 0
(-6 + -12y + (2 * y + 4y * y)) = 0
(-6 + -12y + (2y + 4y2)) = 0

Combine like terms: -12y + 2y = -10y
(-6 + -10y + 4y2) = 0

Solving
-6 + -10y + 4y2 = 0

Subproblem 1
Set the factor '(-1 + -2y)' equal to zero and attempt to solve:

Simplifying
-1 + -2y = 0

Solving
-1 + -2y = 0

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

Add '1' to each side of the equation.
-1 + 1 + -2y = 0 + 1

Combine like terms: -1 + 1 = 0
0 + -2y = 0 + 1
-2y = 0 + 1

Combine like terms: 0 + 1 = 1
-2y = 1

Divide each side by '-2'.
y = -0.5

Simplifying
y = -0.5
Subproblem 2
Set the factor '(3 + -1y)' equal to zero and attempt to solve:

Simplifying
3 + -1y = 0

Solving
3 + -1y = 0

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

Add '-3' to each side of the equation.
3 + -3 + -1y = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -1y = 0 + -3
-1y = 0 + -3

Combine like terms: 0 + -3 = -3
-1y = -3

Divide each side by '-1'.
y = 3

Simplifying
y = 3
Solution
y = {-0.5, 3}
