expand ((4x-5)(x+1))/((7x+8)(x-4))

expand

\frac{( 4 x - 5 ) ( x + 1 )}{( 7 x + 8 ) ( x - 4 )}

\frac{4 x ^{2} - x - 5}{7 x ^{2} - 20 x - 32}

Solution steps

\frac{( 4 x - 5 ) ( x + 1 )}{( 7 x + 8 ) ( x - 4 )}

Expand

(7 x + 8) (x - 4) : 7 x^{2} - 20 x - 32

= \frac{( 4 x - 5 ) ( x + 1 )}{7 x ^{2} - 20 x - 32}

Expand

(4 x - 5) (x + 1) : 4 x^{2} - x - 5

= \frac{4 x ^{2} - x - 5}{7 x ^{2} - 20 x - 32}

\frac{sin ( x ) + tan ( x )}{tan ( x ) ( csc ( x ) + cot ( x ) )}

\frac{( 3 x ^{2} - 10 y ^{4} ) ^{2}}{16}

(x + c)^{2} + y^{2} + 4 a^{2}

\frac{6 x ^{2} - 24 x - 16}{( x - 2 ) ^{2}}

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