解答

展开

\frac{234}{( x + 9 ) ( x - 9 )}

\frac{234}{x ^{2} - 81}

求解步骤

\frac{234}{( x + 9 ) ( x - 9 )}

乘开

(x + 9) (x - 9) : x^{2} - 81

= \frac{234}{x ^{2} - 81}

e x p an d \frac{3 x ^{2} y ^{3} - 1}{( ( 4 + x ^{3} ) y ^{2} )}

e x p an d \frac{1}{( x - 6 ) ^{4}}

e x p an d \frac{15000 ( x - 50 )}{x ^{4}}

e x p an d \frac{1}{50000 ( ( X ) ( X - 7 ) ( X - 14 ) ( X - 33 ) ( X - 40 ) )}

e x p an d (1 + a + a^{2}) (1 - a + a^{2})^{'}
