simplify (7x-2/3)(7x+2/3)

simplify

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

\frac{( 21 x - 2 ) ( 21 x + 2 )}{9}

Solution steps

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

Join

7 x - \frac{2}{3} : \frac{21 x - 2}{3}

= \frac{21 x - 2}{3} (7 x + \frac{2}{3})

Apply the fraction rule:

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

= \frac{( 21 x - 2 ) ( 7 x + \frac{2}{3} )}{3}

Simplify

(21 x - 2) (7 x + \frac{2}{3}) : \frac{( 21 x - 2 ) ( 21 x + 2 )}{3}

= \frac{\frac{( 21 x - 2 ) ( 21 x + 2 )}{3}}{3}

Apply the fraction rule:

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

= \frac{( 21 x - 2 ) ( 21 x + 2 )}{3 \cdot 3}

Multiply the numbers:

3 \cdot 3 = 9

= \frac{( 21 x - 2 ) ( 21 x + 2 )}{9}

\frac{1}{3 ( 11 \cdot 4 ^{x} - 5 )}

\frac{200 e}{( 1 + e ) ^{2}}

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

((1) - sin (x)) (1 + sin (x))
