Question

(8а-3а²+1)-(а-3а²) решите пожалуйста !!!!!!!!

Answer 1

$(8a-3a^2+1)-(a-3a^2)=8a-3a^2+1-a+3a^2=7a+1$

Answer 2

I can help you with your math problem. Here is the detailed solution:

To simplify the expression, we need to apply the distributive property and combine like terms. The distributive property states that $a(b+c) = ab + ac$. Like terms are terms that have the same variable and exponent.

First, we remove the parentheses by multiplying the negative sign with each term inside:

$(8a-3a^2+1)-(a-3a^2) = 8a-3a^2+1-a+3a^2$

Next, we combine the like terms by adding or subtracting their coefficients. The coefficients are the numbers in front of the variables. For example, the coefficient of $8a$ is $8$.

$8a-3a^2+1-a+3a^2 = (8-1)a + (-3+3)a^2 + 1$

$= 7a + 0a^2 + 1$

$= 7a + 1$

This is the final simplified expression.Ответь+подробно.+(8а-3а²+1)-(а-3а²)+решите+пожалуйста+!!!!!!!!
