The expression (8x + 9)(3x² + x - 1) when expanded is 24x³ + 35x² + 17x - 9
How to expand the expression
From the question, we have the following parameters that can be used in our computation:
(8x + 9)(3x² + x - 1)
When the equation is expanded, we have
(8x + 9)(3x² + x - 1) = 24x³ + 8x² + 8x + 27x² + 9x - 9
Collect and evaluate the like terms
This gives
(8x + 9)(3x² + x - 1) = 24x³ + 35x² + 17x - 9
Hence, the expression is 24x³ + 35x² + 17x - 9
