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

expand

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

4 + \frac{8}{x ^{2}}

Solution steps

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

Expand

4 (x^{2} + 2) : 4 x^{2} + 8

= \frac{4 x ^{2} + 8}{x ^{2}}

Apply the fraction rule:

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

\frac{4 x ^{2} + 8}{x ^{2}} = \frac{4 x ^{2}}{x ^{2}} + \frac{8}{x ^{2}}

= \frac{4 x ^{2}}{x ^{2}} + \frac{8}{x ^{2}}

Cancel

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

= 4 + \frac{8}{x ^{2}}

(1 - y) \frac{d y}{d x}

\frac{a}{s ( b s + 1 )}

(i, 1 + 2 i) \cdot (1, 1 - 2 i)

(x + y = 400) (- 200)

(x + (Δ x))^{2}
