Question

(x+3)²-x=(x-2)(x+2)​

Answer 1

Ответ: (x+3)²-x=(x-2)(2+x)

x^2+6x+9-x=x^2-4

x^2-x^2+6x-х=-4-9

5x=-13

x=-13/5

х=-2.6

Answer 2

To solve the given equation, let's simplify it step by step:

(x + 3)² - x = (x - 2)(x + 2)

First, expand the square on the left side:

(x + 3)(x + 3) - x = (x - 2)(x + 2)

(x² + 6x + 9) - x = (x - 2)(x + 2)

x² + 6x + 9 - x = x² - 2²

Next, simplify both sides of the equation:

x² + 5x + 9 = x² - 4

Now, subtract x² from both sides of the equation to eliminate the x² terms:

5x + 9 = -4

Next, subtract 9 from both sides:

5x = -4 - 9

5x = -13

Finally, divide both sides by 5 to solve for x:

x = -13/5

So the solution to the given equation is x = -13/5.
