expand ((x+9)(x+2)(x+4))/((x+6)(x+7))

expand

\frac{( x + 9 ) ( x + 2 ) ( x + 4 )}{( x + 6 ) ( x + 7 )}

\frac{x ^{3} + 15 x ^{2} + 62 x + 72}{x ^{2} + 13 x + 42}

Solution steps

\frac{( x + 9 ) ( x + 2 ) ( x + 4 )}{( x + 6 ) ( x + 7 )}

Expand

(x + 6) (x + 7) : x^{2} + 13 x + 42

= \frac{( x + 9 ) ( x + 2 ) ( x + 4 )}{x ^{2} + 13 x + 42}

Expand

(x + 9) (x + 2) (x + 4) : x^{3} + 15 x^{2} + 62 x + 72

= \frac{x ^{3} + 15 x ^{2} + 62 x + 72}{x ^{2} + 13 x + 42}

\frac{( x ^{2} + 4 x + 3 ) ( x + 1 )}{36}

f (x) 3 t + 4 (g (x, t) = - 3)

\frac{1}{( 1 - 5 x ) ^{- \frac{1}{4}}}

(sin (a) + cos (b)) (sin (b) + cos (a))

p^{\frac{1}{4}} (p^{\frac{3}{4}} + 3 p^{\frac{7}{4}})
