Question

4. Expand each of the following, using suitable identities (p+1)3​

Answer 1

Answer:

We need to find value of (p+1)  

3

 

Suitable identities is (x+y)  

3

=x  

3

+3x  

2

y+3xy  

2

+y  

3

 

Here x=p and y=1

Therefore, value of (p+1)  

3

 is

=(p)  

3

+3(p)  

2

(1)+3(p)(1)  

2

+(1)  

3

 

=p  

3

+3p  

2

+3p+1
