Impara online a risolvere i problemi di calcolo differenziale passo dopo passo. ((x+a)^(-2)-x^(-2))/a. Applicare la formula: x^a=\frac{1}{x^{\left|a\right|}}. Applicare la formula: a+\frac{b}{c}=\frac{b+ac}{c}, dove a=\frac{1}{\left(x+a\right)^{2}}, b=-1, c=x^{2}, a+b/c=\frac{1}{\left(x+a\right)^{2}}+\frac{-1}{x^{2}} e b/c=\frac{-1}{x^{2}}. Applicare la formula: a+\frac{b}{c}=\frac{b+ac}{c}, dove a=-1, b=x^{2}, c=\left(x+a\right)^{2}, a+b/c=-1+\frac{x^{2}}{\left(x+a\right)^{2}} e b/c=\frac{x^{2}}{\left(x+a\right)^{2}}. Applicare la formula: \frac{\frac{a}{b}}{c}=\frac{a}{bc}, dove a=\frac{x^{2}-\left(x+a\right)^{2}}{\left(x+a\right)^{2}}, b=x^{2}, c=a, a/b/c=\frac{\frac{\frac{x^{2}-\left(x+a\right)^{2}}{\left(x+a\right)^{2}}}{x^{2}}}{a} e a/b=\frac{\frac{x^{2}-\left(x+a\right)^{2}}{\left(x+a\right)^{2}}}{x^{2}}.
