展开 sqrt(5(x+h)-g(x)+2)

解答

展开

5 (x + h) - g (x) + 2

5 x + 5 h - xg + 2

求解步骤

5 (x + h) - g (x) + 2

去除括号:

(a) = a

= 5 (x + h) - gx + 2

乘开

5 (x + h) - gx + 2 : 5 x + 5 h - gx + 2

= 5 x + 5 h - xg + 2

e x p an d \frac{( n - s ) ( ( n - s ) - 1 )}{2}

e x p an d y (b - a y^{2}) d y

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

e x p an d \frac{( 10 - j ) ( - 8 - 9 j )}{- 10 j + 2}

e x p an d 8 (- 0.4 e^{- 0.4 x} + 0.6 e^{- 0.6 x})
