Question

(p+1)²-(p-1)² I need this Asap​

Answer 1

Answer:

4p

Step-by-step explanation:

Identity used here – a² - b² = (a+b)(a-b)

(p+1)² - (p-1)²

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

= (2p) (2)

= 4p

Answer 2

Answer:

0

Step-by-step explanation:

(p+1)²-(p-1)² = a²-b²

Using identity: a² - b² = (a + b)×(a - b)

(a + b)×(a - b) = (p+1+p-1)×(p+1-p-1)

⇒ 2p×0 = 0

∴ (p+1)²-(p-1)² = 0
