The degree of the difference is 1.
Step-by-step explanation:
Sum of (4 + 3x) and (5 - 4x + 2x²) = 4 + 3x + 5 - 4x + 2x² = 2x² - x + 9
Sum of (3x² - 5x) and (-x² + 2x + 5) = 3x² - 5x - x² + 2x + 5 = 2x² - 3x + 5
Difference = (2x² - x + 9) - (2x² - 3x + 5)
= 2x² - x + 9 - 2x² + 3x - 5
= 2x + 4
Degree is the power of leading coefficient.
Leading coefficient of the difference is 2x.
Power of 2x is 1.
Hence, the degree of the difference is 1.
