Question

What is the factor form of n2-25

Answer 1

N²-25 = n²-5² = (n+5)(n-5)

Answer 2

Answer:

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

                 $(n-5)(n+5)$

Step-by-step 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:

               $n^2-25=(n-5)(n+5)$
