simplify (-2)/i

Solution

simplify

\frac{- 2}{i}

2 i

Solution steps

\frac{- 2}{i}

Multiply by the conjugate

\frac{- i}{- i}

= \frac{- 2 ( - i )}{i ( - i )}

Simplify

\frac{- 2 ( - i )}{i ( - i )} : \frac{2 i}{1}

= \frac{2 i}{1}

Apply the fraction rule:

\frac{a}{1} = a

= 2 i

\frac{8}{9} \cdot \frac{5}{11} \cdot \frac{1}{2}

4 z^{2} - 9

\frac{3 + i 3}{4 + i 6}

(x - 4) (3 x + 4) = 0

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