Question

ou Find each the following products: (a) =

(a^2 - 3a + 7) × (2a + 3)​

Answer 1

$\tt(2a + 3)( {a}^{2} - 3a + 7)$

$\tt2a( {a}^{2} - 3a + 7) + 3( {a}^{2} - 3a + 7)$

$\tt {2a}^{3} - {6a}^{2} + 14a + 3 {a}^{2} - 9a + 21$

Adding the like terms,

$\tt2 {a}^{3} + 3 {a}^{2} - 6 {a}^{2} + 14 a- 9a + 21$

$\tt2 {a}^{3} - 3 {a}^{2} + 5a + 21$
