simplify (1-(sqrt(3))/3)(1+(sqrt(3))/3)

simplify

(1 - \frac{3}{3}) (1 + \frac{3}{3})

\frac{2}{3}

Decimal Notation

0.66666 \dots

Solution steps

(1 - \frac{3}{3}) (1 + \frac{3}{3})

1 - \frac{3}{3} = \frac{3 - 1}{3}

= \frac{3 - 1}{3} (1 + \frac{3}{3})

Cancel

\frac{3}{3} : \frac{1}{3}

= \frac{3 - 1}{3} (1 + \frac{1}{3})

Expand

\frac{3 - 1}{3} (1 + \frac{1}{3}) : \frac{2}{3}

= \frac{2}{3}

(5 + 1) (3 + 2)

\frac{1}{( s + 8 ) ( s ^{2} - 2 s + 2 )}

\frac{4 x ^{2} - 2 x + 1}{( x + 3 ) ^{3} ( x ^{2} - 7 ) ^{2}}

(1 + cos (x))^{2} + sin^{2} (x)

\frac{( sin ( x ) cos ( x ) + 1 ) ^{2}}{sin ^{2} ( x ) cos ^{2} ( x )}
