$(5x+2)(5x-2)$
$\bf{\text{Solution Outline:}}$ To factor the given expression, $25x^2-4 ,$ use the factoring of the difference of $2$ squares. $\bf{\text{Solution Details:}}$ Using $a^2-b^2=(a+b)(a-b)$ or the factoring of the diffrence of $2$ squares, the factored form of the expression above is \begin{array}{l}\require{cancel} (5x+2)(5x-2) .\end{array}
