化简 (3sqrt(x)-7)(6sqrt(x)-2)

解答

化简

(3 x - 7) (6 x - 2)

18 x - 48 x + 14

求解步骤

(3 x - 7) (6 x - 2)

Apply FOIL method

(3 x - 7) (6 x - 2) : 18 x - 48 x + 14

= 18 x - 48 x + 14

e x p an d (x^{3} + 2^{x}) e^{x + x}

e x p an d - \frac{( x + 1 ) ( x - 3 ) ( x - 5 )}{320}

s im pl i f y 4 (x^{2} - 8 x + 12 x^{\frac{4}{3}} - 6 x^{\frac{4}{3}} 3 x)

e x p an d A (- 3, - 6, - 3) y B (- 5, 4, - 7)

e x p an d \frac{0.25 ( s + 4 )}{s ^{3} + 8 s ^{2} + 12 s + 10}
