expand (9x(7x+9))/((9x-7)^2)

expand

\frac{9 x ( 7 x + 9 )}{( 9 x - 7 ) ^{2}}

\frac{63 x ^{2} + 81 x}{81 x ^{2} - 126 x + 49}

Solution steps

\frac{9 x ( 7 x + 9 )}{( 9 x - 7 ) ^{2}}

(9 x - 7)^{2} = 81 x^{2} - 126 x + 49

= \frac{9 x ( 7 x + 9 )}{81 x ^{2} - 126 x + 49}

Expand

9 x (7 x + 9) : 63 x^{2} + 81 x

= \frac{63 x ^{2} + 81 x}{81 x ^{2} - 126 x + 49}

\frac{x - 5}{2 x ( 3 x - 4 )}

x^{2} (2 ln (x) + 5)

(3, 2 n) - (2 + m, 5)

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

(2 x + 3) + (2 y - 2) y^{'} (x)
