化简 (sqrt(x+5))*(x+2)

解答

化简

(x + 5) \cdot (x + 2)

(x + 2) x + 5

求解步骤

(x + 5) (x + 2)

使用法则:

(a) = a

(x + 5) = x + 5

= x + 5 (x + 2)

= (x + 2) x + 5

e x p an d (D^{2} - 5) {e^{5 x} cos (2 x)}

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

e x p an d - 2 (- C (sin (x)) - D (cos (x)))^{2}

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

e x p an d (1 - x^{2}) (L ((1 - x^{2})^{\frac{m ^{2}}{2}} - m^{2} x^{2} (1 - x^{2})^{\frac{m ^{2}}{2} - 1}))
