expand (25(1-x^2))/(x^2)

expand

\frac{25 ( 1 - x ^{2} )}{x ^{2}}

\frac{25}{x ^{2}} - 25

Solution steps

\frac{25 ( 1 - x ^{2} )}{x ^{2}}

Expand

25 (1 - x^{2}) : 25 - 25 x^{2}

= \frac{25 - 25 x ^{2}}{x ^{2}}

Apply the fraction rule:

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

\frac{25 - 25 x ^{2}}{x ^{2}} = \frac{25}{x ^{2}} - \frac{25 x ^{2}}{x ^{2}}

= \frac{25}{x ^{2}} - \frac{25 x ^{2}}{x ^{2}}

Cancel

\frac{25 x ^{2}}{x ^{2}} : 25

= \frac{25}{x ^{2}} - 25

\frac{36 x ^{4}}{9 x ^{2}}

0.4 (0.4 y = 0.3 x + 1.2)

\frac{( ( x + 2 ) ( x - 1 ) ( x - 3 ) )}{6}

im x \Rightarrow 2 (2 x^{2} + 2 x)

\frac{( y - 2 ) d y}{( y - 3 ) ( y - 1 )}
