A= 3×(x+5)

A= 3×x + 3×5

A= 3x + 15

B= 3x × (-4+x)

B= -3x × 4 + 3x×x

B= -12x + 3x²

C= 3(b-4)

C= 3×b - 3×4

C= 3b - 12

D= -w(-1+w)

D= w×1 - w×w

D= w - w²

E= -4(7+u)

E= -4×7 - 4×u

E= -28 - 4u

F= -2y(3y+5)

F= -2y×3y - 2y×5

F= -6y² - 10y

G= -2(5x-1)

G= -2×5x + 2×1

G= -10x + 2

H= -3a(6-5a)

H= -3a×6 + 3a×5a

H= -18a + 15a²
