Question

(p+1)^2-(p+2)^2 ??????

Answer 1

(p+1)^2-(p+2)^2 = ( p + 1 + p + 2 )( p + 1 - p - 2 ) = ( 2p + 3 )*( - 1 ) = - 2p - 3 

Answer 2

Answer 3

Using the identity (a + b)(a - b) = a^2 - b^2, we can simplify the expression:

(p+1)^2 - (p+2)^2

= [(p+1) + (p+2)][(p+1) - (p+2)]

= (2p + 3)(-1)

= -2p - 3

Therefore, (p+1)^2 - (p+2)^2 simplifies to -2p - 3.
