# How do you simplify (t^-25)/(t^+t-20)?

${t}^{- 25} / \left(t + t - 20\right) = \frac{1}{2 {t}^{26} - 20 {t}^{25}}$
${t}^{- 25} / \left({t}^{2} + t - 20\right) = \frac{1}{{t}^{25} \left(t + 5\right) \left(t - 4\right)}$
${t}^{- 25} / \left({t}^{t} - 20\right) = \frac{1}{{t}^{25 + t} - 20 {t}^{25}}$
