化简 (x-11-sqrt(3))(x-2)(x-4)(x-11+sqrt(3))

解答

化简

(x - 11 - 3) (x - 2) (x - 4) (x - 11 + 3)

(x^{2} - 22 x + 118) (x - 2) (x - 4)

求解步骤

(x - 11 - 3) (x - 2) (x - 4) (x - 11 + 3)

打开括号

= (xx + x (- 11) + x 3 - 11 x - 11 (- 11) - 113 - 3 x - 3 (- 11) - 33) (x - 2) (x - 4)

化简

xx + x (- 11) + x 3 - 11 x - 11 (- 11) - 113 - 3 x - 3 (- 11) - 33 : x^{2} - 22 x + 118

= (x^{2} - 22 x + 118) (x - 2) (x - 4)

e x p an d (2, - 2) (2 x, 3) (4, 3)

e x p an d 1 (4 x + 5 y = 22.25)

e x p an d \frac{125 ( 10 + 73 )}{2}

e x p an d \frac{1}{( arctan ( x ) + c ) ^{2}}

e x p an d l im x \Rightarrow 2 (x^{2} + x - 6 x - 2)
