## teenandtoddlermom 3 years ago need a check (4-z)z= Multiply and Simplify 4z^2?

1. anonymous

no sorry

2. anonymous

you have to multiply each term in the parentheses by $$z$$

3. anonymous

$$4-z\neq 4z$$

4. teenandtoddlermom

4xz-zxz=4z

5. teenandtoddlermom

or am I doing this wrong...

6. anonymous

$(4-z)z=4\times z-z\times z$

7. anonymous

8. anonymous

$4\times z=4z$ $-z\times z=z^2$

9. anonymous

you should get $4z-z^2$
