expand ((4-t^2)(5t-3))/((4t+3)(5t+1))

expand

\frac{( 4 - t ^{2} ) ( 5 t - 3 )}{( 4 t + 3 ) ( 5 t + 1 )}

\frac{20 t - 12 - 5 t ^{3} + 3 t ^{2}}{20 t ^{2} + 19 t + 3}

Solution steps

\frac{( 4 - t ^{2} ) ( 5 t - 3 )}{( 4 t + 3 ) ( 5 t + 1 )}

Expand

(4 t + 3) (5 t + 1) : 20 t^{2} + 19 t + 3

= \frac{( - t ^{2} + 4 ) ( 5 t - 3 )}{20 t ^{2} + 19 t + 3}

Expand

(4 - t^{2}) (5 t - 3) : 20 t - 12 - 5 t^{3} + 3 t^{2}

= \frac{20 t - 12 - 5 t ^{3} + 3 t ^{2}}{20 t ^{2} + 19 t + 3}

M (3, 6) y N (3, - 6)

\frac{( 6 x ^{2} - 2 )}{( 1 + x ^{2} ) ^{3}}

\frac{20 - 23}{\frac{12.55}{53}}

\frac{1}{( cos ( x ) \cdot ( 1 - x ) )}

\frac{20 ( s + 2 )}{s ( s ^{2} + 6 s + 25 )}
