simplify (9/(x-12)+3(100-x))(x-12)

simplify

(\frac{9}{x - 12} + 3 (100 - x)) (x - 12)

- 3 x^{2} + 336 x - 3591

Solution steps

(\frac{9}{x - 12} + 3 (100 - x)) (x - 12)

Join

\frac{9}{x - 12} + 3 (100 - x) : \frac{- 3 x ^{2} + 336 x - 3591}{x - 12}

= \frac{- 3 x ^{2} + 336 x - 3591}{x - 12} (x - 12)

Cross-cancel common factor:

x - 12

= - 3 x^{2} + 336 x - 3591

\frac{a x ^{2} + b x + c}{( x ^{2} + 1 ) ( x - 3 )}

12 (lo g_{a} (b) + lo g_{b} (c))

2^{2} + 3^{2}

\frac{2 ( k + 1 ) ( k + 2 ) ( 2 k + 2 )}{3}

\frac{K ( s ^{2} + 4 s + 8 )}{s ^{3} + s ^{2}}
