Question

p square -1 factorise​

Answer 1

p²-1 = (p+1)(p-1)

Since, a²-b² = (a+b)(a-b)

Answer 2

Answer:

p² - 1² = (p + 1) (p - 1)

Step-by-step explanation:

p² - 1   ...   (i)

Equation (i) can be written as p² - 1²

We know that, a² - b² = (a+b) (a-).

Here, a = p and b = 1

So, p² - 1² = (p + 1) (p - 1)
