Use the distributive property: a(b-c)=ab-ac

Answer 17

I dont knoe the distributie Prop

Answer 18

It tells you how to get rid of the brackets!
So you have to multiply -1/2 with 4 and also multiply -1/2 with -6a

Answer 19

okay I see

Answer 20

What do you get?

Answer 21

how do I multiply a fraction in to a number

Answer 22

Just forget the "-" for a while.
1/2 * 4 means you have four halves. How many is that?

Answer 23

2 wholes

Answer 24

OK. Now remember that if you multiply a negative number with a positive number, the outcome is negative.

So: -1/2 * 4 = ...

Answer 25

-2

Answer 26

Right!, now the other one...

Answer 27

so for the other half it be-3 the i would be left with(-2- -3) and my answer be -5

Answer 28

You have to multiply, so -1/2 * -6a = ...

Answer 29

6 isn't negative that was the subtraction sign

Answer 30

OK, so save it for later. So: -1/2 * 6a = ...

Answer 31

-3

Answer 32

You lost the a

Answer 33

-3a ugh srry:p

Answer 34

so then my equation would be(-2 - -3a)

Answer 35

the my answer should be -5a right

Answer 36

No, -2 hasn't got an a with it, so you can't add it to 3a

Answer 37

So it would be -2+3a

Answer 38

-- = +

Answer 39

so it be 1a right

Answer 40

No, it would be -2+3a.
This cannot be written shorter!

If it was -2a+3a this would be 1a or a.

Answer 41

oh okay got it
