Question

Expand the following:

a).

`8(x - 2y)`
b).

`(6a + 18b - 12c)/(6)`
​

Answer 1

8x - 16y and a + 3b - 2c

Explanation:

(a)

8(x - 2y) ← multiply each term in the parenthesis by 8

= 8x - 16y

(b)

`(6a+18b-12c)/(6)` ← factor out 6 from each term in the numerator

=
`(6(a+3b-2c))/(6)` ← cancel the 6 on numerator/ denominator

= a + 3b - 2c

Answer 2

8x-16y

Explanation:

• b.6a/6+18b/6-12c/6
