x\left(-\frac{2}{169}\right)x+30
Divide x\times \frac{2}{13} by -13 to get x\left(-\frac{2}{169}\right).
x^{2}\left(-\frac{2}{169}\right)+30
Multiply x and x to get x^{2}.
\frac{2\left(-xx+2535\right)}{169}
Factor out \frac{2}{169}. Polynomial -x^{2}+2535 is not factored since it does not have any rational roots.
