The solutions to the equation are 3 and -5.
To solve any equation is to find the solution of the given equation which satisfied the equation.
The given expression is
let u = (x +2)
then the equation becomes
by factorizing, we get
(u + 3)(u - 5) = 0
u + 3 = 0, u = -3
u - 5 = 0, u = 5
Since, u = x + 2
So, x + 2 = 5, x = 3
x + 2 = -3, x = -5
Therefore, the solutions to the equation are 3 and -5.
