To solve the equation (х+2)²+2(х+2)-3=0, we can start by simplifying it.
First, let's expand the squared term (х+2)² to get rid of the square:
(х+2)² = (х+2)(х+2) = х² + 2х + 2х + 4 = х² + 4х + 4
Now let's substitute this back into the equation:
(х+2)² + 2(х+2) - 3 = 0 (х² + 4х + 4) + 2(х+2) - 3 = 0 х² + 4х + 4 + 2х + 4 - 3 = 0 х² + 6х + 5 = 0
Now, we have a quadratic equation in standard form: ax² + bx + c = 0, where a = 1, b = 6, and c = 5. We can solve this quadratic equation by factoring, completing the square, or using the quadratic formula. Let's solve it by factoring:
(x + 1)(x + 5) = 0
To find the values of x, we set each factor equal to zero:
x + 1 = 0 or x + 5 = 0
Solving these equations separately, we get:
x = -1 or x = -5
So the solutions to the equation are x = -1 and x = -5.
