Question

Expand and simplify : 6(p+6)-3(p+3)

Answer 1

We have the expression

`6(p + 6) - 3(p + 3)`
We expand each bracket first, to obtain,


`6(p + 6) - 3(p + 3)=6p + 36 - 3p - 9`
Be mindful of the negative sign.

We now group like terms,


`6(p + 6) - 3(p + 3)=6p - 3p + 36 - 9`
and then simplify to obtain,


`6(p + 6) - 3(p + 3)=3p + 27`
