Question

40a2 + a-6 factories​

Answer 1

Answer:

Your answer:

=40a² + a - 6

=40a² +16a - 15a - 6

=8a(5a + 2) - 3(5a + 2)

=(8a - 3) (5a + 2)

Therfore, factors are (8a - 3) (5a + 2)

Hope it helps you!

Answer 2

Given : The algebraic expression is, 40a²+a-6

To find : The factorisation of the given algebraic expression.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to factorise the given algebraic expression)

Here, we will be using the general algebraic method to factorise the given algebraic expression.

So,

= 40a²+a-6

= 40a²+16a-15a-6

= 8a(5a+2) -3(5a+2)

= (5a+2) (8a-3)

(This cannot be further factorised. That's why this will be considered as the final result.)

Hence, the answer to the factorisation is, (5a+2) (8a-3)
