Question

What is the product of (5x+1)(5x-1)

Answer 1

Answer: The required product is
`25x^2-1.`

Step-by-step explanation: We are given to find the following product :

`P=(5x+1)(5x-1)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)`

We will be using the following formula :

`(a+b)(a-b)=a^2-b^2.`

From (i), we get

`P\\\\=(5x+1)(5x-1)\\\\=(5x)^2-1^2\\\\=25x^2-1.`

Thus, the required product is
`25x^2-1.`

Answer 2

25x²-1
