解答

展开

\frac{17 ( x ^{2} + y ^{2} )}{6 y + 37 x}

\frac{17 x ^{2} + 17 y ^{2}}{6 y + 37 x}

求解步骤

\frac{17 ( x ^{2} + y ^{2} )}{6 y + 37 x}

乘开

17 (x^{2} + y^{2}) : 17 x^{2} + 17 y^{2}

= \frac{17 x ^{2} + 17 y ^{2}}{6 y + 37 x}

e x p an d 5 4 a^{2}

e x p an d f (g (2 - x))

e x p an d \frac{x ^{2}}{( ( 0.025 - x ) \cdot ( 0.2 - x ) )}

e x p an d \frac{y ( 6 t - sin ( 6 t ) )}{36}

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