Question

Simplify the following polynomial expression:

(5x² – 9x + 2) + (-3x² + 2x + 7) + (2x²+ 3) (22 – 5)
a. 4x⁴ – 5x² – 7x - 6
b. 4x⁴– 5x² + 7x + 6
c. 4x⁴ – 9x² – 7x + 24
d. 4x⁴ - 9x² – 7x – 24

Answer 1

To simplify the polynomial expression, combine like terms to get 4x⁴ - 9x² - 7x + 24.

Step-by-step explanation:

To simplify the polynomial expression, we need to combine like terms. Like terms have the same variables and the same exponent.

By combining like terms, we get (5x² - 3x² + 2x²) + (-9x + 2x) + (2 + 3) * (22 - 5).

This simplifies to 4x⁴ - 5x² - 7x + 24. Therefore, the correct answer is option c) 4x⁴ - 9x² - 7x + 24.
