2a^2+2a+1-7a^3

Answer 2

To simplify the expression (2a²-3a+1)-(7aa²-5a), we can distribute the negative sign to each term inside the parentheses and then combine like terms.

First, let's distribute the negative sign: (2a²-3a+1) - (7aa²-5a) = 2a² - 3a + 1 - 7aa² + 5a

Next, let's combine like terms. We have two terms with a², two terms with a, and one constant term:

2a² - 3a + 1 - 7aa² + 5a = (2a² - 7aa²) + (-3a + 5a) + 1

Combining the like terms, we get:

(2a² - 7aa²) + (-3a + 5a) + 1 = -5aa² + 2a + 1

Therefore, the simplified expression is -5aa² + 2a + 1.
