Question

Simplify the expression 3a (12 – 8) + 2 ( 3 + 12a)

Answer 1

3a ( 12 - 8 ) + 2 ( 3 + 12 a)
you can simplify what is in the parentheses of (12-8) so that is your first step.
this becomes
3a(4) + 2(3+12a)
From there you distribute the 2 to the values in (3+12a) , distribution is simply multiplying to each term.
and multiply the 3 from 3a to the 4.
you have.
12a + 2(3) + 2(12a)
multiply
12a + 6 + 24 a
then just combine the like terms.

Answer 3

you simply need to distribute the numbers outside your parenthesis into the numbers inside
so 3a(12-8) would be 36a-24a (U multiply number outside with number inside parenthesis) and 2(3+12a) would be 6+24a
when you put them together you get 36a-24a+6+24a so you then combine like terms giving you
36a+6
since -24a and 24a cancel
