因式分解 (t-3)^{7/2}-(t-3)^{3/2}

解答

因式分解

(t - 3)^{\frac{7}{2}} - (t - 3)^{\frac{3}{2}}

解答

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

求解步骤

(t - 3)^{\frac{7}{2}} - (t - 3)^{\frac{3}{2}}

将

(t - 3)^{\frac{7}{2}}

改写为

(t - 3)^{7}

= (t - 3)^{7} - (t - 3)^{\frac{3}{2}}

将

(t - 3)^{\frac{3}{2}}

改写为

(t - 3)^{3}

= (t - 3)^{7} - (t - 3)^{3}

因式分解出通项

(t - 3)^{3} : (t - 3)^{3} ((t - 3)^{4} - 1)

= (t - 3)^{3} ((t - 3)^{4} - 1)

分解

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

= (t - 3)^{3} ((t - 3)^{2} + 1) (t - 3 + 1) (t - 3 - 1)

化简

(t - 3)^{3} ((t - 3)^{2} + 1) (t - 3 + 1) (t - 3 - 1) : (t - 3)^{3} (t - 2) (t - 3 + 1) (t - 3 - 1)

= (t - 3)^{3} (t - 2) (t - 3 + 1) (t - 3 - 1)

(t - 3)^{3} = (t - 3)^{\frac{3}{2}}

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