展开 asqrt(b+(x-h)^2)+k

解答

展开

a b + (x - h)^{2} + k

a b + x^{2} - 2 h x + h^{2} + k

求解步骤

a b + (x - h)^{2} + k

b + (x - h)^{2} = b + x^{2} - 2 h x + h^{2}

= a x^{2} - 2 h x + b + h^{2} + k

\frac{\partial}{\partial x} ((f (x, y)) (y^{5} - 3 x y))

e x p an d \frac{( 8 x ^{6} - 9 ) ^{2}}{576 x ^{6}}

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

e x p an d \frac{y + 2 z - x}{( y + 2 z ) ^{2}}

\frac{\partial}{\partial u} ((f (u)) (1, - 1))
