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

\frac{x ^{2} + x ^{2} 3 x - 1 + 4 3 x - 1}{x ^{2} + 4}

求解步骤

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

乘开

x^{2} + (x^{2} + 4) 3 x - 1 : x^{2} + x^{2} 3 x - 1 + 4 3 x - 1

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

e x p an d (- 4 r^{4} cos (θ) - 4 r sin (θ) + r)^{2}

e x p an d (e^{15 x} + e^{- 15 x})^{2}

e x p an d \frac{a + 8}{( a - 2 ) ( a - 9 )}

e x p an d - \frac{4 ( x + 4 ) ^{2}}{9}

e x p an d \frac{X ^{2}}{2} - 2 X + \frac{3}{2}
