Steps
result
(2x - 3)( 5x2 – 2x+7)
use the distributive property to multiply
2x times each term in the trinomial.
10x3 - 4x2 + 14x
(result for this step only)
2 use the distributive property to multiply
-3 times each term in the trinomial.
10x - 4x? + 14x – 15x² - 6x-
(result for step 1 and 2)
| 10² – 19x² + 144 – 6x-21
3 use the addition property to combine
the x? terms.
4 use the addition property to combine
the x terms
10x3 - 19x2 +8x-21
