Q. 4 E4.3( 13 Votes )

# Expand each of the following, using suitable identities

(p + 1)^{3}

Answer :

Using identity (x + y)^{3} = x^{3} + y^{3} + 3x^{2}y + 3xy^{2}

Here x = p and y = 1

⇒ (p + 1)^{3} = p^{3} + 1^{3} + 3(p)^{2}(1) + 3(p)(1)^{2}

= p^{3} + 1^{3} + 3p^{2} + 3p

Therefore (p + 1)^{3} = p^{3} + 1^{3} + 3p^{2} + 3p
