Question

(7x² - 2x + 3) -(6x + 4x² - 1) =СРОЧНО РЕБЯТАА​

Answer 1

Ответ: 7х^2-2х+3-6х-4х^2+1=3х^2-8х+4

Answer 2

To simplify the given expression, let's first combine like terms:

(7x² - 2x + 3) - (6x + 4x² - 1)

= 7x² - 2x + 3 - 6x - 4x² + 1

Now, let's group the x² terms and the x terms together:

(7x² - 4x²) + (-2x - 6x) + (3 + 1)

= (7 - 4)x² + (-2 - 6)x + (3 + 1)

= 3x² - 8x + 4

Therefore, the simplified expression is 3x² - 8x + 4.
