8x= -8

x= -1

Answer 2

Let's simplify and solve the equation step by step:

(х + 2)^2 + 4х = (х - 2)(х + 2)

Expanding the left side of the equation: (х + 2)(х + 2) + 4х = (х - 2)(х + 2)

Simplifying the left side: (x^2 + 4x + 4) + 4x = (x - 2)(x + 2)

Expanding the right side: x^2 + 4x + 4 + 4x = x^2 - 2x + 2x - 4

Combining like terms: x^2 + 8x + 4 = x^2 - 4

Subtracting x^2 from both sides: 8x + 4 = -4

Subtracting 4 from both sides: 8x = -8

Dividing both sides by 8: x = -1

So the solution to the equation is x = -1.
