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


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

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

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

Multiply (3 + 2y) * (5 + y)
(3(5 + y) + 2y * (5 + y)) = -2(2y + 3)
((5 * 3 + y * 3) + 2y * (5 + y)) = -2(2y + 3)
((15 + 3y) + 2y * (5 + y)) = -2(2y + 3)
(15 + 3y + (5 * 2y + y * 2y)) = -2(2y + 3)
(15 + 3y + (10y + 2y2)) = -2(2y + 3)

Combine like terms: 3y + 10y = 13y
(15 + 13y + 2y2) = -2(2y + 3)

Reorder the terms:
15 + 13y + 2y2 = -2(3 + 2y)
15 + 13y + 2y2 = (3 * -2 + 2y * -2)
15 + 13y + 2y2 = (-6 + -4y)

Solving
15 + 13y + 2y2 = -6 + -4y

Solving for variable 'y'.

Reorder the terms:
15 + 6 + 13y + 4y + 2y2 = -6 + -4y + 6 + 4y

Combine like terms: 15 + 6 = 21
21 + 13y + 4y + 2y2 = -6 + -4y + 6 + 4y

Combine like terms: 13y + 4y = 17y
21 + 17y + 2y2 = -6 + -4y + 6 + 4y

Reorder the terms:
21 + 17y + 2y2 = -6 + 6 + -4y + 4y

Combine like terms: -6 + 6 = 0
21 + 17y + 2y2 = 0 + -4y + 4y
21 + 17y + 2y2 = -4y + 4y

Combine like terms: -4y + 4y = 0
21 + 17y + 2y2 = 0
