a^5+2a^3+3a^2-5a^3-10a-15

a^5+7a^3+3a^2-10a-15. (ans.)

Answer 2

Step-by-step explanation:

$( {a}^{2} - 5)( {a}^{3} - 2a + 4a + 3) \\ ( {a}^{2} - 5)( {a}^{3} + 2a + 3) \\ {a}^{2} ( {a}^{3} + 2a + 3) - 5({a}^{3} + 2a + 3) \\ {a}^{5} + 2 {a}^{3} + 3 {a}^{2} - 5 {a}^{3} - 10a - 15 \\ {a}^{5} - 3 {a}^{3} + 3 {a}^{2} - 10a - 15$
