\frac{3 x + 11}{( x + 3 ) ( 3 x + 1 )}

\frac{3 x + 11}{3 x ^{2} + 10 x + 3}

求解步骤

\frac{3 x + 11}{( x + 3 ) ( 3 x + 1 )}

乘开

(x + 3) (3 x + 1) : 3 x^{2} + 10 x + 3

= \frac{3 x + 11}{3 x ^{2} + 10 x + 3}

e x p an d (t sin (t^{2})) (sin (t^{2}) + 2 t^{2} cos (t^{2}))

e x p an d x (x^{2} + y^{2}) x^{2} + y^{2}
