simplify (y-3/7)*(y+3/7)

simplify

(y - \frac{3}{7}) \cdot (y + \frac{3}{7})

\frac{( 7 y - 3 ) ( 7 y + 3 )}{49}

Solution steps

(y - \frac{3}{7}) (y + \frac{3}{7})

Simplify

y - \frac{3}{7} : \frac{7 y - 3}{7}

= \frac{7 y - 3}{7} (y + \frac{3}{7})

Apply the fraction rule:

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

= \frac{( 7 y - 3 ) ( y + \frac{3}{7} )}{7}

Simplify

(7 y - 3) (y + \frac{3}{7}) : \frac{( 7 y - 3 ) ( y \cdot 7 + 3 )}{7}

= \frac{\frac{( 7 y - 3 ) ( y \cdot 7 + 3 )}{7}}{7}

Apply the fraction rule:

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

= \frac{( 7 y - 3 ) ( y \cdot 7 + 3 )}{7 \cdot 7}

Multiply the numbers:

7 \cdot 7 = 49

= \frac{( 7 y - 3 ) ( y \cdot 7 + 3 )}{49}

= \frac{( 7 y - 3 ) ( 7 y + 3 )}{49}

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

cos (2 (x + π))

π (25 x - x^{3})

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

\frac{3 ( 401 - 1 )}{5}
