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

expand

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

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

Solution steps

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

Expand

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

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

Join

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

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

\frac{2 x - 5}{( 2 x - 4 ) ( x - 4 ) ( x - 5 )}

\frac{- 4 x ^{3} + 1}{2 x ^{\frac{1}{2}} ( x ^{3} + 1 ) ^{2}}

(x + 3) (x + 1) (0.2 x) (\frac{1}{2})

(2 x^{3} + 9 x^{2} + 3 x - 4) d i v i d e (x + 4)

\frac{d}{d x} ((f (x, y)) f (x, y) (x^{3} - 3 x y + y^{2}))
