化简 (x^2-2)(sqrt(x^2-6x+5))

解答

化简

(x^{2} - 2) (x^{2} - 6 x + 5)

(x^{2} - 2) x^{2} - 6 x + 5

求解步骤

(x^{2} - 2) (x^{2} - 6 x + 5)

使用法则:

(a) = a

(x^{2} - 6 x + 5) = x^{2} - 6 x + 5

= (x^{2} - 2) x^{2} - 6 x + 5

e x p an d, 150 (2 s - 150) - (2 s - 150)^{2} + 300 s - 2 s^{2}

e x p an d 9 (\frac{16}{4} - 231 = \frac{524}{3})

e x p an d (5 t + e^{(- 2 t)} cos (7 t)) u (t)

e x p an d \frac{a ( t - 2 )}{3}

e x p an d (\frac{18 - V ( a ) a}{6} + 3 = \frac{V ( a ) a}{10}) 30
