expand (x+9)left(x-3)

expand

(x + 9) l e f t (x - 3)

e l x^{2} f t + 6 e l x f t - 27 e l f t

Solution steps

(x + 9) l e f t (x - 3)

= e l f t (x + 9) (x - 3)

Expand

(x + 9) (x - 3) : x^{2} + 6 x - 27

= l e f t (x^{2} + 6 x - 27)

Expand

l e f t (x^{2} + 6 x - 27) : e l x^{2} f t + 6 e l x f t - 27 e l f t

= e l x^{2} f t + 6 e l x f t - 27 e l f t

\frac{5 t ^{2} + 21 t + 10}{2 t ( t + 5 ) ( t + 2 )}

\frac{( 2 x - 2 - a x ) ( 1 + a ) ( 1 - a )}{2 a}

t (x) x^{^{''}} + (4 t (x) - 2) x^{^{'}} + 4 x

\frac{d}{d y} ((x) (2 x + 1))

\frac{sec ^{2} ( x ) ( x ^{2} + 1 ) ^{6}}{( e ^{x} - cos ^{2} ( x ) ) ^{4}}
