expand (c-d)(e-f)

Solution

expand

(c - d) (e - f)

Solution

ec - c f - e d + df

Solution steps

(c - d) (e - f)

Apply FOIL method:

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

a = c, b = - d, c = e, d = - f

= ce + c (- f) + (- d) e + (- d) (- f)

Apply minus-plus rules

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

= ec - c f - e d + df
