expand (d-e)(f-g)

Solution

expand

(d - e) (f - g)

Solution

df - d g - e f + e g

Solution steps

(d - e) (f - g)

Apply FOIL method:

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

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

= df + d (- g) + (- e) f + (- e) (- g)

Apply minus-plus rules

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

= df - d g - e f + e g
