Question

factorise: a2 - 3a - 40

Answer 1

Here is ur answer hope it helps

Answer 2

The factories form is $a^2-3a-40=(a-8)(a+5)$

Step-by-step explanation:

Given : Polynomial $a^2-3a-40$.

To find : Factories the polynomial ?

Solution :

Polynomial $a^2-3a-40$.

Applying middle term split,

$a^2-3a-40=a^2-8a+5a-40$

$a^2-3a-40=a(a-8)+5(a-8)$

$a^2-3a-40=(a-8)(a+5)$

The factories form is $a^2-3a-40=(a-8)(a+5)$.
