Question

Expand and simplify 3(2x - 5) - 4(x + 3)​

Answer 1

Answer:

3(2x + 5) - 2(x-4) becomes

(3 x 2x) + (3 x 5) + (-2 x x) + (-2 x -4) =

6x + 15 - 2x + 8 (remember that '-' x '-' = '+')

Then you need to do something called 'collecting the like terms'. This means collecting together all the 'x' terms and all of the 'number' terms, like this:

6x + 15 - 2x + 8 becomes

(6x - 2x) + (15 + 8), working this out means the answer is:

4x + 23
