Question

What is the factor form of n2-25

Answer 1

n²-25 = n²-5² = (n+5)(n-5)

Answer 2

The factor form of:
`n^2-25` is:

`(n-5)(n+5)`

Explanation:

Factor form--

It means that the expression is represented by factoring the expression.

i.e. we find out the roots of the expression and then express it as a product of it's linear factors.

The expression is given by:

`n^2-25`

We know that any expression of the form:

`a^2-b^2` could be written in the form:

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

Here we have:

`n^2-25=n^2-5^2\\\\i.e.\\\\n^2-25=(n-5)(n+5)`

Hence, the answer is:

`n^2-25=(n-5)(n+5)`
