Question

3p . (2+k) = 6p + 3pk

Answer 1

`3p* (2+k) = 6p + 3pk`

Subtract
`6 p + 3 pk` from the both sides:


`3p(2+k) -(6p+3pk) = 6p+3pk-(6p+3pk)`


`= 3pk(2+k) - 6p-3pk = 0`

Factor
`3p(2+k) - 6p - 3k`

Factor out common term
`3p`


`= 3p(k-k+2-2)`

refine:


`0 = 0`

true for all
`p`

hope this helps!
