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}

\frac{3}{2 ( 2 t - 1 )}

\frac{1}{5 x}

(6 x - 2 y = 1, 2) (12 x - 4 y = 14)

\frac{10}{s ( s ^{2} + 4 )}

(3 (y + 2) d x - x d y = 0) \frac{1}{x d x}
