Step-by-step explanation:
First of all we'll find the sum of 9 + 4x and 6 - 3x + 5x²
9 + 4x + 6 - 3x + 5x²
= 9 + 6 + 4x - 3x + 5x²
= 15 + x + 5x²
Secondly, now we'll find the sum of 4x² - 5x and -2x² + 4x + 5
4x² - 5x + (-2x² + 4x + 5)
= 4x² - 5x - 2x² + 4x + 5
= 4x² - 2x² - 5x + 4x + 5
= 2x² - x + 5
Now difference of both
15 + x + 5x² - (2x² - x + 5)
= 15 + x + 5x² - 2x² + x - 5
= 15 - 5 + x - x + 5x² - 2x²
= 10 + 3x²
May the answer helps you!!!
