Solution for (y+3)(y-4)=y(y-5)+2(y+6) equation:


Simplifying
(y + 3)(y + -4) = y(y + -5) + 2(y + 6)

Reorder the terms:
(3 + y)(y + -4) = y(y + -5) + 2(y + 6)

Reorder the terms:
(3 + y)(-4 + y) = y(y + -5) + 2(y + 6)

Multiply (3 + y) * (-4 + y)
(3(-4 + y) + y(-4 + y)) = y(y + -5) + 2(y + 6)
((-4 * 3 + y * 3) + y(-4 + y)) = y(y + -5) + 2(y + 6)
((-12 + 3y) + y(-4 + y)) = y(y + -5) + 2(y + 6)
(-12 + 3y + (-4 * y + y * y)) = y(y + -5) + 2(y + 6)
(-12 + 3y + (-4y + y2)) = y(y + -5) + 2(y + 6)

Combine like terms: 3y + -4y = -1y
(-12 + -1y + y2) = y(y + -5) + 2(y + 6)

Reorder the terms:
-12 + -1y + y2 = y(-5 + y) + 2(y + 6)
-12 + -1y + y2 = (-5 * y + y * y) + 2(y + 6)
-12 + -1y + y2 = (-5y + y2) + 2(y + 6)

Reorder the terms:
-12 + -1y + y2 = -5y + y2 + 2(6 + y)
-12 + -1y + y2 = -5y + y2 + (6 * 2 + y * 2)
-12 + -1y + y2 = -5y + y2 + (12 + 2y)

Reorder the terms:
-12 + -1y + y2 = 12 + -5y + 2y + y2

Combine like terms: -5y + 2y = -3y
-12 + -1y + y2 = 12 + -3y + y2

Add '-1y2' to each side of the equation.
-12 + -1y + y2 + -1y2 = 12 + -3y + y2 + -1y2

Combine like terms: y2 + -1y2 = 0
-12 + -1y + 0 = 12 + -3y + y2 + -1y2
-12 + -1y = 12 + -3y + y2 + -1y2

Combine like terms: y2 + -1y2 = 0
-12 + -1y = 12 + -3y + 0
-12 + -1y = 12 + -3y

Solving
-12 + -1y = 12 + -3y

Solving for variable 'y'.

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

Add '3y' to each side of the equation.
-12 + -1y + 3y = 12 + -3y + 3y

Combine like terms: -1y + 3y = 2y
-12 + 2y = 12 + -3y + 3y

Combine like terms: -3y + 3y = 0
-12 + 2y = 12 + 0
-12 + 2y = 12

Add '12' to each side of the equation.
-12 + 12 + 2y = 12 + 12

Combine like terms: -12 + 12 = 0
0 + 2y = 12 + 12
2y = 12 + 12

Combine like terms: 12 + 12 = 24
2y = 24

Divide each side by '2'.
y = 12

Simplifying
y = 12
