Answer:
The correct answer is option B.
5x⁵ + -8x³ + x² + 5x -1
Step-by-step explanation:
It is given that,
(x³ + 2x⁴ + 5x⁵ - 2x - 1) - (-7x - x² + 9x³ + 2x⁴)
<u>To find the subtraction result</u>
(x³ + 2x⁴ + 5x⁵ - 2x - 1) - (-7x - x² + 9x³ + 2x⁴)
= x³ + 2x⁴ + 5x⁵ - 2x - 1 + 7x + x² - 9x³ - 2x⁴)
= 5x⁵ + 2x⁴ - 2x⁴ + x³ - 9x³ + x²- 2x + 7x -1
= 5x⁵ + -8x³ + x² + 5x -1
The correct answer is option B.
5x⁵ + -8x³ + x² + 5x -1
