Question

(n + 1)2 – n2 = (n + 1) + n OR 2n + 1
plzzzz prove it​

Answer 1

Step-by-step explanation:

(n+1)²-n²=2n+1

LHS

n²+2n+1-n²

2n+1

hence, LHS=RHS

(n+1)²-n²=(n+1)+n

LHS

[(n+1)+n]X[(n+1)-n]

[(n+1)+n]X[n+1-n]

[(n+1)+n]x1

(n+1)+n

hence, LHS=RHS

mark me as brainlist

Answer 2

according to question: -->

n square +1+2n - n square as 2n +1 first one is proved that 2n+1 =2n+1.

also it is to proved that n square +n =as well as (n+1)n=

n square +2n -n square +1= n(n+2-n)+1=let be (n+2-n)=n as n+1(n)also (n+1)(n).

hence proved hopes u like this mark it as a brainlist ans. &follow me . also rate this answer.
