simplify (7/(x-12)+6(100-x))(x-12)

simplify

(\frac{7}{x - 12} + 6 (100 - x)) (x - 12)

- 6 x^{2} + 672 x - 7193

Solution steps

(\frac{7}{x - 12} + 6 (100 - x)) (x - 12)

Join

\frac{7}{x - 12} + 6 (100 - x) : \frac{- 6 x ^{2} + 672 x - 7193}{x - 12}

= \frac{- 6 x ^{2} + 672 x - 7193}{x - 12} (x - 12)

Cross-cancel common factor:

x - 12

= - 6 x^{2} + 672 x - 7193

\frac{5}{7} \cdot (1 + ln (\frac{7}{5}))

sin (x) (1 - cos (x)) (1 + sec (x))

\frac{q l ^{2} ( 10 - l )}{120}

\frac{x - t + 1}{( - t + x ) ( t + x ) ( t - x )}

4 x^{3} (x^{2})
