I know the answer is -5z to the power of 3 can some one show me how to expand and simplify it
-5z(z2-2z-5)
Please help ! The 2 after the "z" (z2) is "z" squared! :)

-5z^3 +10z^2 + 25z
Powers can be expressed with the ^
a^2 is a squared.

using the distributive property
(-5z)(z^2) + (-5z)(-2z) + (-5z)(-5)
-5z*z^2 + 10z*z + 25z
-5z^3 + 10z^2 + 25z
are you sure its -5z to the third power?
(-5z)(z^2) + (-5z)(-2z) + (-5z)(-5)
-5z*z^2 + 10z*z + 25z
-5z^3 + 10z^2 + 25z
are you sure its -5z to the third power?

After expansion, (^ means to the power of)
First term is -5z^3
Second term is +10z^2
Third term is +25z
Since the second and third term will not cancel each other, the answer is NOT -5Z^3
First term is -5z^3
Second term is +10z^2
Third term is +25z
Since the second and third term will not cancel each other, the answer is NOT -5Z^3

first thing you need to do is multiply -5z*(z^2)=-z^3
then multiply (-5z)*(-2z)=10z^2
then multiply (-5z)*(-5)=25z
When you add up all of the answers you get -5z^3+10z^2+25z.
then multiply (-5z)*(-2z)=10z^2
then multiply (-5z)*(-5)=25z
When you add up all of the answers you get -5z^3+10z^2+25z.

-5z^3 + 10z^2 + 25z is the answer :)
-5z(z^2) + -5z(-2z) + -5z(-5)
