Answer 2

Let's simplify the given expression step by step:

First, let's expand both sides of the equation:

(x - 2)(x + 2) = 3(x + 4)^2 - 2x(x + 5)

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

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

Expanding the right side: 3(x + 4)^2 - 2x(x + 5) = 3(x^2 + 8x + 16) - 2x^2 - 10x

Simplifying the right side: 3(x^2 + 8x + 16) - 2x^2 - 10x = 3x^2 + 24x + 48 - 2x^2 - 10x = x^2 + 14x + 48

Now, we can rewrite the equation with the simplified expressions:

x^2 - 4 = x^2 + 14x + 48

Next, let's simplify the equation further:

x^2 - x^2 - 14x = 48 - 4

Simplifying: -14x = 44

Dividing both sides by -14: x = -44/14 x = -22/7

Therefore, the solution to the equation is x = -22/7.
