Question

factorise the following expression x^2-6x-72​

Answer 1

Answer:

x^2-12x+6x-72

x(x-12)+6(x-12)

(x-12) (x+6)

Please follow me mate

It's a humble request mate.

Answer 2

The answer to the factorisation is, (x-12) (x+6)

Given : The given algebraic expression is, x²-6x-72

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 applying general algebraic formula.

So,

= x²-6x-72

= x²-12x+6x-72

= x(x-12) + 6(x-12)

= (x-12) (x+6)

(This will be considered as the final result.)

Hence, the answer to the factorisation is, (x-12) (x+6)
