expand ((x^2+4))/(x^2)

expand

\frac{( x ^{2} + 4 )}{x ^{2}}

1 + \frac{4}{x ^{2}}

Solution steps

\frac{x ^{2} + 4}{x ^{2}}

Apply the fraction rule:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{x ^{2} + 4}{x ^{2}} = \frac{x ^{2}}{x ^{2}} + \frac{4}{x ^{2}}

= \frac{x ^{2}}{x ^{2}} + \frac{4}{x ^{2}}

Apply rule

\frac{a}{a} = 1

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

= 1 + \frac{4}{x ^{2}}

(x + e^{2 x}) \cdot (3 x + e^{2 x})

(t^{2} - x t^{2}) \frac{d x}{d x}

\frac{2 ( 6 + 3 )}{3}

2 [x y (3 x + 3 y)] + x^{3} + y^{3} - 3 x y

- 5^{2}
