expand-(36(7x-y)(x+7y))/(25)

expand

- \frac{36 ( 7 x - y ) ( x + 7 y )}{25}

- \frac{252 x ^{2}}{25} - \frac{1728 x y}{25} + \frac{252 y ^{2}}{25}

Solution steps

- \frac{36 ( 7 x - y ) ( x + 7 y )}{25}

Expand

36 (7 x - y) (x + 7 y) : 252 x^{2} + 1728 x y - 252 y^{2}

= - \frac{252 x ^{2} + 1728 x y - 252 y ^{2}}{25}

Apply the fraction rule:

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

\frac{252 x ^{2} + 1728 x y - 252 y ^{2}}{25} = - (\frac{252 x ^{2}}{25}) - (\frac{1728 x y}{25}) - (- \frac{252 y ^{2}}{25})

= - (\frac{252 x ^{2}}{25}) - (\frac{1728 x y}{25}) - (- \frac{252 y ^{2}}{25})

Remove parentheses:

(a) = a, - (- a) = a

= - \frac{252 x ^{2}}{25} - \frac{1728 x y}{25} + \frac{252 y ^{2}}{25}

\frac{x ^{2} + a}{( x - 4 ) ( x + 5 )}

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

\frac{12 t + 9}{( t - 1 ) ( t - 4 )}

(2^{-} 2 + 2) (2^{-} 2 + 2)

\frac{10 x}{( 5 x - 3 ) ( 2 x + 1 ) ^{2}}
