Question

p2 - 2p - 3
factorise this​

Answer 1

Answer:

P-3 ,P +1

Step-by-step explanation:

p2 - 2p -3

= p2 + 1p - 3p - 3

= p(p+1) - 3(p+1)

= (p-3)(p+1)

Answer 2

Given : The given algebraic expression is, p²-2p-3

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 general method of algebraic factorisation. (we may use algebraic identities also, if necessary)

So, the factorisation will be :

= p²-2p-3

= p²+p-3p-3

= p(p+1) - 3(p+1)

= (p+1) (p-3)

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

Hence, the answer to the factorisation is (p+1) (p-3)
