simplify (x+1/3)*(x-1/3)

simplify

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

\frac{( 3 x + 1 ) ( 3 x - 1 )}{9}

Solution steps

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

Simplify

x + \frac{1}{3} : \frac{3 x + 1}{3}

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

Apply the fraction rule:

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

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

Simplify

(3 x + 1) (x - \frac{1}{3}) : \frac{( 3 x + 1 ) ( x \cdot 3 - 1 )}{3}

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

Apply the fraction rule:

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

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

Multiply the numbers:

3 \cdot 3 = 9

= \frac{( 3 x + 1 ) ( x \cdot 3 - 1 )}{9}

= \frac{( 3 x + 1 ) ( 3 x - 1 )}{9}

a (2 + cos (2 θ))^{2}

(x + 2) (x - 1) (x - (4 + i)) (x - (4 - i))

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

(a, b) (b, - a)

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