Answer:
6x³ + x² - 9x +10
Step-by-step explanation:
This one uses typical FOIL multiplication.
We are given the expression (3x + 5) (2
– 3x + 2)
Using FOIL, we multiply every term in all ways. We can rewrite the expression as (3x · 2
) + (3x · -3x) + (3x · 2) + (5 · 2
) + (5 · -3x) + (5 · 2)
Which simplifies to 6x³ - 9x² + 6x + 10x²- 15x + 10
Which we can further simplify to 6x³ + x² - 9x +10
