a. x × 1
b. x × a × 4
c. 6x(-x) × (-2)
d. b × 3 × (a-c)
e. x × (-2) + y × 4
f. c × 4 × a
g. b × a × (-2) × a

Answer 1

a. x × 1 => 1.x = x
b. x × a × 4 => 4.a.x = 4ax
c. 6x(-x) × (-2) => 6x(-x.-2) => 6x(2x) = (6.2)(x.x) = 12x²
d. b × 3 × (a-c) => 3b(a-c) = 3ab-3bc
e. x × (-2) + y × 4 => (x.-2)+(y.4) = -2x+4y atau 4y-2x
f. c × 4 × a => (4.a.c) = 4ac
g. b × a × (-2) × a=> -2(a.a)b = -2a²b
