Question

Simplify the following expression.
(2x – 3)(5x⁴ – 7x³ + 6x² – 9)​

Answer 1

10x⁵ - 29x⁴ + 33x³ - 18x² - 18x + 27

Explanation:

All we have to do is distribute both terms of the binomial into the polynomial and combine like terms.

10x⁵ - 14x⁴ + 12x³ - 18x - 15x⁴ + 21x³ - 18x² + 27

10x⁵ - 29x⁴ + 33x³ - 18x² - 18x + 27
