expand (x-e)(x-23)

Solution

expand

(x - e) (x - 23)

Solution

x^{2} - 23 x - e x + 23 e

Solution steps

(x - e) (x - 23)

Apply FOIL method:

(a + b) (c + d) = a c + a d + b c + b d

a = x, b = - e, c = x, d = - 23

= xx + x (- 23) + (- e) x + (- e) (- 23)

Apply minus-plus rules

+ (- a) = - a, (- a) (- b) = ab

= xx - 23 x - e x + 23 e

xx = x^{2}

= x^{2} - 23 x - e x + 23 e
