Question

Y=√x²+12x+20(9класс)​

Answer 1

Ответ:

y=x+12x+20=13x+20

Пошаговое объяснение:

✓x- во второй степени

формула

х во второй степени равняется х

х+12х=13х

а 13х+20 не слаживается потому-что они не подобные

Answer 2

The given equation is:

Y = √(x² + 12x + 20)

To solve this equation, we can follow these steps:

Step 1: Factorize the expression inside the square root, if possible. The expression x² + 12x + 20 cannot be easily factored, so we move to the next step.

Step 2: Complete the square. To complete the square, we need to add and subtract a constant term that will allow us to factorize the quadratic expression. The constant we add is half the coefficient of x squared, which is (12/2)² = 36.

Y = √((x² + 12x + 36) - 36 + 20)

Simplifying further:

Y = √((x + 6)² - 16)

Step 3: Apply the square root property. The square root of a difference of squares can be written as the difference of their square roots.

Y = √(x + 6 - 4) * √(x + 6 + 4)

Simplifying further:

Y = √(x + 2) * √(x + 10)

So the simplified form of the equation is:

Y = √(x + 2) * √(x + 10)

Please note that this is the simplified form of the equation, but it cannot be further solved without additional information or constraints.
