Question

α' _ ο
8α +15
factorization by splitting the middle term​

Answer 1

Given :

• Factorise a²+8a+15 . (correct)

Answer:

⇒a²+8a+15 .

⇒a² + 5a + 3a + 15.

⇒a(a+5)+3(a+5)

⇒(a+3)(a+5).

Note:

• We have here used middle term splitting method to factorise the given expression

Answer 2

Answer:

a*2 + 8a + 15

a*2 +( 5a + 3a) + 15

a(a+5) +3 (a+5)

(a+5)(a+3)
