化简 (x)(sqrt(x+2)+2)

解答

化简

(x) (x + 2 + 2)

x (x + 2 + 2)

求解步骤

(x) (x + 2 + 2)

使用法则:

(a) = a

(x) = x

= x (x + 2 + 2)

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

e x p an d (- 9, 7) y (- 9, - 1)

e x p an d \frac{( 5 y + 1 ) ^{2}}{25}

e x p an d (x + 3) l e f t (x - 4)

e x p an d \frac{1}{s ^{2} ( s + 6 )}
