展开 (y(y-3))/(y^2-y+1)

解答

展开

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

\frac{y ^{2} - 3 y}{y ^{2} - y + 1}

求解步骤

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

乘开

y (y - 3) : y^{2} - 3 y

= \frac{y ^{2} - 3 y}{y ^{2} - y + 1}

e x p an d (2 x - y = 1, 8) - (3 x + 2 y = 13)

e x p an d \frac{( x + 3 ) ( x + 6 )}{2}

e x p an d (1, - 2) (x, y)

e x p an d (2) (4 x + 3 y = 9)

e x p an d (58)^{3}
