10a^2-7a+2-6a^2+7a+8
4a^2+2+8
4a^2+10
Ответ:4a^2+10

Answer 2

To simplify the expression (10a² - 7a + 2) - (6a² - 7a - 8), you can distribute the negative sign to every term inside the second set of parentheses and then combine like terms:

(10a² - 7a + 2) - (6a² - 7a - 8)

= 10a² - 7a + 2 - 6a² + 7a + 8

Now, combine like terms:

(10a² - 6a²) + (-7a + 7a) + (2 + 8)

= 4a² + 0a + 10

= 4a² + 10

So, the simplified expression is 4a² + 10.
