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

1. satellite73

no sorry

2. satellite73

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

3. satellite73

$$4-z\neq 4z$$

4. teenandtoddlermom

4xz-zxz=4z

5. teenandtoddlermom

or am I doing this wrong...

6. satellite73

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

7. satellite73

8. satellite73

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

9. satellite73

you should get $4z-z^2$
