Question

How do you factor 8z^3-75z=0?

Answer 1

pull out a z and you'll get a squared function

Answer 2

then use quadratic formula if you'd lik

Answer 3

Factorising is when you take a common term out of the equation and use it to make the equation simpler.

In your case, the common term we can take out is z, but also whatever is a factor of both 8 and 75.

Answer 4

\[8z ^{3}-75z=0\]
\[z(8z ^{2}-75)=0\]
\[z(2z \sqrt{2}+5\sqrt{3})(2z \sqrt{2}-5\sqrt{3})=0\]
