Answer:
2x² + 2x + 7
Step-by-step explanation:
It is given that, two expressions
2x² - 6x - 4 and 4x² - 4x + 3
To find the subtraction result
4x² - 4x + 3 - (2x² - 6x - 4 )
= 4x² - 4x + 3 - 2x² + 6x + 4
= 4x² - 2x² - 4x + 6x + 3 + 4
= 2x² + 2x + 7
Therefore the result for subtraction is 2x² + 2x + 7
