Question

Factorize a^3 + 2a^2 + 5a +10

Answer 1

Question:-

Factorise the given Polynomial.

Solution:-

$\sf {a}^{3} + 2{a}^{2} + 5a + 10$

$\sf = {a}^{2} (a + 2) + 5(a + 2)$

$\sf = ( {a}^{2} + 5)(a + 2)$

Hence, the factorised form is (a²+5)(a+2).

Answer 2

Step-by-step explanation:

a³+2a²+5a+10

a²(a+2)+5(a+2)

(a²+5)(a+2)
