Let's first simplify the equation:
5 - 2y^2 + (y + 1)(2y - 1) = 75 - 2y^2 + 2y^2 - y + 2y - 1 = 7Combine like terms:5 - y - 1 = 74 - y = 7Isolate y:-y = 7 - 4-y = 3y = -3
Therefore, the solution to the equation is y = -3.
Let's first simplify the equation:
5 - 2y^2 + (y + 1)(2y - 1) = 7
5 - 2y^2 + 2y^2 - y + 2y - 1 = 7
Combine like terms:
5 - y - 1 = 7
4 - y = 7
Isolate y:
-y = 7 - 4
-y = 3
y = -3
Therefore, the solution to the equation is y = -3.
