simplify x^2-(1/x)^2+2x(1/x)

Solution

simplify

x^{2} - (\frac{1}{x})^{2} + 2 x (\frac{1}{x})

Solution

x^{2} - \frac{1}{x ^{2}} + 2

Solution steps

x^{2} - (\frac{1}{x})^{2} + 2 x (\frac{1}{x})

Apply rule:

(a) = a

(\frac{1}{x}) = \frac{1}{x}

= x^{2} - (\frac{1}{x})^{2} + 2 x \frac{1}{x}

(\frac{1}{x})^{2} = \frac{1}{x ^{2}}

2 x \frac{1}{x} = 2

= x^{2} - \frac{1}{x ^{2}} + 2
