Question

(х+11)степ 2 -х в степ 2=11

Answer 1

На второй строчке x^2 уничтожаются

Answer 2

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

1. Distribute the exponent to both terms: (х + 11)² - х² = 11

2. Expand the squared terms: (х + 11)(х + 11) - х² = 11

3. Multiply the binomials: х² + 11х + 11х + 121 - х² = 11

4. Combine like terms: 22х + 121 = 11

5. Move the constant term to the right side: 22х = 11 - 121

6. Simplify the right side: 22х = -110

7. Finally, solve for х by dividing both sides by 22: х = -110 / 22 х = -5

So, the solution to the equation is х = -5.
