Question

(7x в квадрате-5x+3)-(7x в квадрате-5)=

Answer 1

7x²-5x+3-7x²+5= 8-5x

Answer 2

$( {7x}^{2} - 5x + 3) - ( {7x}^{2} - 5) = \\ {7x}^{2} - 5x + 3 - {7x}^{2} + 5 = \\ - 5x + 8$

Answer 3

To solve the expression (7x² - 5x + 3) - (7x² - 5), we need to distribute the negative sign inside the parentheses.

(7x² - 5x + 3) - (7x² - 5) = 7x² - 5x + 3 - 7x² + 5

Next, we can combine like terms:

7x² - 7x² - 5x + 5 + 3 = -5x + 8

Therefore, the simplified form of the expression is -5x + 8.
