Just started a calculus course. Its been awhile since I've done any algebra. I used to be good at math, I just need some help to get started.

HINT: Simply take it as $f(x)=x^2(x^2-10^7)$. I think we can see our roots very clearly now


We can write $f(x)=x^2*(x^2-10^7)$ and we want to find where $f(x)=0$. We can do this by finding $x$ such that either $(x^2-10^7)=0$ or $x^2=0$.
