longdivision ((2x-5))/((3-4x))

解答

长除法

\frac{( 2 x - 5 )}{( 3 - 4 x )}

- \frac{1}{2} - \frac{7}{2 ( - 4 x + 3 )}

求解步骤

\frac{( 2 x - 5 )}{( 3 - 4 x )}

对

\frac{2 x - 5}{- 4 x + 3}

做除法:

\frac{2 x - 5}{- 4 x + 3} = - \frac{1}{2} + \frac{- \frac{7}{2}}{- 4 x + 3}

= - \frac{1}{2} + \frac{- \frac{7}{2}}{- 4 x + 3}

化简

= - \frac{1}{2} - \frac{7}{2 ( - 4 x + 3 )}

l o n g d i v i s i o n \frac{( n + 2 )}{( n + 1 )}

l o n g d i v i s i o n \frac{( a + 2 )}{( a - 2 )}

l o n g d i v i s i o n \frac{( 2 x ^{2} + 4 x + 3 )}{( 4 x + 2 )}

l o n g d i v i s i o n \frac{( 2 x + 3 )}{( x + 1 )}

l o n g d i v i s i o n \frac{( 2 x ^{2} - x - 21 )}{( x ^{2} - 1 )}
