expand (x-89)left(x-91)

expand

(x - 89) l e f t (x - 91)

e l x^{2} f t - 180 e l x f t + 8099 e l f t

Solution steps

(x - 89) l e f t (x - 91)

= e l f t (x - 89) (x - 91)

Expand

(x - 89) (x - 91) : x^{2} - 180 x + 8099

= l e f t (x^{2} - 180 x + 8099)

Expand

l e f t (x^{2} - 180 x + 8099) : e l x^{2} f t - 180 e l x f t + 8099 e l f t

= e l x^{2} f t - 180 e l x f t + 8099 e l f t

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

(x + 2 x - y - 2 y) (x + y)

(6 + 14 i)^{4}

a (t - sin (t))
