can someone help me with the following: find the product of -3a^3b(2a^0b^4 - 4a^2b^3) Thanks much!
Yes, for the first one, you just multiply it out term by term.
There are common terms in the 2nd one, though.
$\displaystyle 3z^3-300z=0$
$\displaystyle 3z(z^2-100)=0$
z could be zero or $\displaystyle z^2$ could be 100
Remember 100 has a positive and negative square root.
