Factor 25t^2-1 - Math App

Math

$25 t^{2} - 1$

Rewrite $25 t^{2}$ as ${(5 t)}^{2}$ .

${(5 t)}^{2} - 1$

Rewrite $1$ as $1^{2}$ .

${(5 t)}^{2} - 1^{2}$

Since both terms are perfect squares, factor using the difference of squares formula, $a^{2} - b^{2} = (a + b) (a - b)$ where $a = 5 t$ and $b = 1$ .

$(5 t + 1) (5 t - 1)$

Factor 25t^2-1
