Answer 2

Answer: 2x² - 8x + 9

Step-by-step explanation: this is our initial equation:

(4x² – 3x + 2) - (2x² + 5x - 7)

the subtraction sign which is to the left values is multiplying to the values into the parenthesis

(-) * (2x² + 5x - 7)

so this factor change the sign to every value into the parenthesis, then we get the following equation.

-2x² - 5x + 7

after this we get this final equation

4x² – 3x + 2 - 2x² - 5x + 7

then we resolve the equation with the similar values

4x² - 2x² = 2x²

– 3x - 5x = - 8x

+ 2 + 7 = 9

after this we place values in one equation, and we get the form simplified

2x² - 8x + 9

and this the last equation after resolve all the problems into the parenthesis.
