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

expand

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

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

Solution steps

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

(1 - X)^{2} = 1 - 2 X + X^{2}

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

Apply the fraction rule:

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

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

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

Divide the numbers:

\frac{2}{2} = 1

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

Rewrite in standard form

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

F (- G + B = N)

\frac{x}{6 ( x ^{2} - 36 )}

\frac{3 ( 14 - x )}{4}

- 6 (5 x + 1 = 3 x - 6)

\frac{( 2 z + 1 ) ( 4 z - 1 )}{2}
