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

= ec + c f - e d - df
