Question

(7x²-4x-8)-(4x^x -5)​

Answer 1

Ответ:

$7x {}^{2} - 4x - 3 - 4x {}^{x}$

Answer 2

It looks like you want to subtract one polynomial from another. Let's perform the subtraction step by step:

Polynomial 1: 7x² - 4x - 8 Polynomial 2: 4x^2 - 5

To subtract Polynomial 2 from Polynomial 1, you should change the sign of every term in Polynomial 2 and then combine like terms:

(7x² - 4x - 8) - (4x^2 - 5)

Now, distribute the negative sign to every term in Polynomial 2:

7x² - 4x - 8 - 4x² + 5

Now, combine like terms by adding or subtracting coefficients of the same power of x:

(7x² - 4x²) + (-4x - 8 + 5)

Combine the x² terms:

3x² + (-4x - 8 + 5)

Combine the constant terms:

3x² - 4x - 3

So, the result of subtracting (7x² - 4x - 8) from (4x^2 - 5) is:

3x² - 4x - 3
