化简 (3sqrt(x)-2)(2sqrt(x)+5)

解答

化简

(3 x - 2) (2 x + 5)

6 x + 11 x - 10

求解步骤

(3 x - 2) (2 x + 5)

Apply FOIL method

(3 x - 2) (2 x + 5) : 6 x + 11 x - 10

= 6 x + 11 x - 10

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

e x p an d (A + B x) e^{3 x}

e x p an d \frac{( 3 x + 1 ) ^{4} ( x - 4 )}{( x ^{2} + 1 ) ^{3} sin ( x )}

e x p an d \frac{24 - 4 x}{3 ( 8 - x ) ^{\frac{2}{3}}}

e x p an d \frac{( s + 10 )}{( s ^{2} + 0.1 s + 1 ) ^{2}}
