lcm \delta(x-yy_{2}),y_{2}

解答

lcm

δ (x - y y_{2}), y_{2}

δ (x - y y_{2}) y_{2}

求解步骤

找到

δ (x - y y_{2}), y_{2}

的最小公倍数

将最高次数乘以每个因数:

δ (x - y y_{2}) \cdot y_{2}

e x p an d \frac{3 x ^{2} + x ^{4}}{x ^{5}}

e x p an d, 4 ((\frac{1}{2}) + i (\frac{3}{2}))

s im pl i f y \frac{1}{4} (1.2 - 1) + \frac{1}{2}

e x p an d - 5 (- 4 - 2)

e x p an d \frac{12 ab}{a ^{2} b ^{2}}
