x\left(49y^{2}-25\right)
Factor out x.
\left(7y-5\right)\left(7y+5\right)
Consider 49y^{2}-25. Rewrite 49y^{2}-25 as \left(7y\right)^{2}-5^{2}. The difference of squares can be factored using the rule: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
x\left(7y-5\right)\left(7y+5\right)
Rewrite the complete factored expression.
