how do u expand brackets easily

1 Answer

Hi Kelcy!

Here is an example: 15f+10

All you do is you see what times table goes into both of them numbers so in this case: 5. So you write 5 before the bracets.

Then you see what number you times using 5 to get to that number and you put that in the bracets.

So the answer is 5(3f+2)

Hope this helped!
