Question

How do I expand 4(-2y + 3), and whats the answer when expanded?

1. -8y + 12

2. 2y + 7

3. -8y + 3

4. 2y + 12

Answer 1

the answer is 1. -8y+12

Explanation:

4(-2y+3)

4 times -2y -8y

4 times +3 12

Put them together and you get -8y+12

As the 4 is on the outside of the bracket, you must multiply everything on the inside of the bracket by 4.

Answer 2

To expand the equation, multiply the number outside the parenthesis by each term inside the parentheses:

4(-2y + 3) =

4 * -2y + 4 *3 =

-8y + 12
