Subtract (2x³ + 9x − 8) − (4x² − 15x + 7).
Let's use the concept of adding and subtracting polynomials to evaluate the result.
Answer: (2x³ + 9x − 8) − (4x² − 15x + 7) = 2x³ - 4x² + 24x - 15
Let's solve the given expression (2x³ + 9x − 8) − (4x² − 15x + 7)
Explanation:
(2x³ + 9x − 8) − (4x² − 15x + 7) = 2x³ - 4x² + 9x + 15x - 8 - 7
= 2x³ - 4x² + 24x - 15
Hence, (2x³ + 9x − 8) − (4x² − 15x + 7) = 2x³ - 4x² + 24x - 15
