Question

factor this polynomial expression x^2-25

Answer 1

Answer:

x^2-25

Step-by-step explanation:

rewrite 25 as 5^2

x^2-5^2

since both terms are perfect squares, factor using the difference of square s formula, a^2-b^2=(a+b)(a-b) where a=x and b=5

(x+5)(x-5)

plz mark me as brainliest if this helped :)

Answer 2

Answer:

$\[(x+5)*(x-5)\]$

Step-by-step explanation:

Given polynomial expression is $\[x^{2}-25\]$

$\[=> x^{2}-5^{2}\]$

This is of the form $\[a^{2}-b^{2}\]$

An expression of this form can be factorized as $\[(a+b)*(a-b)\]$

Here, a = x and b = 5.

Hence the factorized form of the given polynomial expression can be represented as the following product:

$\[(x+5)*(x-5)\]$
