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.
