Step-by-step explanation:
9x² + 8x - 2x² - 3x
= (9x² - 2x²) + (8x - 3x)
= 7x² + 5x.
The difference between the polynomials is 7x² + 5x
From the equation
(9x2 + 8x) – (2x2 + 3x)
Expand the bracket first
9x² + 8x - 2x² - 3x
Collect like terms
9x² - 2x² + 8x - 3x
7x² + 5x
Thus, the difference between the polynomials is 7x² + 5x
