expand (ax+by)(c+dy)

Solution

expand

(a x + b y) (c + d y)

Solution

a c x + a x d y + b cy + b y d y

Solution steps

(a x + b y) (c + d y)

Apply FOIL method:

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

a = a x, b = b y, c = c, d = d y

= a x c + a x d y + b yc + b y d y

= a c x + a x d y + b cy + b y d y
