expand (x+e)(x-pi)

Solution

expand

(x + e) (x - π)

Solution

x^{2} - π x + e x - e π

Solution steps

(x + e) (x - π)

Apply FOIL method:

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

a = x, b = e, c = x, d = - π

= xx + x (- π) + e x + e (- π)

Apply minus-plus rules

+ (- a) = - a

= xx - π x + e x - e π

xx = x^{2}

= x^{2} - π x + e x - e π
