\frac{4-625x^{2}}{25}
Factor out \frac{1}{25}.
\left(2-25x\right)\left(2+25x\right)
Consider 4-625x^{2}. Rewrite 4-625x^{2} as 2^{2}-\left(25x\right)^{2}. The difference of squares can be factored using the rule: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
\left(-25x+2\right)\left(25x+2\right)
Reorder the terms.
\frac{\left(-25x+2\right)\left(25x+2\right)}{25}
Rewrite the complete factored expression.
