comment How do you integrate $\int x(x+3)^ \left( 1/3 \right) dx$
I apologize for not being clear. I did substitute the $x$ with $u-3$, but the form of the equation seems similar. It didn't occur to me that the new form can be distributed, while the old one cannot.

comment What is the intuitive meaning of the basis of a vector space and the span?
Is there an upper bound on the number of matrices that can be used as a basis for $\mathbb R ^2$, like the one you have shown above?

$b$ is nonzero.

comment How do I calculate the quartiles for this problem?
There is some confusion between the answers by EpicGuy and Sim. My source agrees with the former, while the quartiles calculator at alcula.com/calculators/statistics/quartiles agrees with the latter. I would appreciate it if someone could resolve this.

BTW, I am the OP. I was finally able to log into my own account.

Your answer doesn't agree with the other answer posted by EpicGuy. It also doesn't agree with my original source from where I took the problem. I like your method, but the other answer is the correct one. I'd like to know how to get the correct answer using this method. Could you please double-check this? Thanks.

comment Intersection point of 2 circles
Sorry, what I meant was, you substitute out whatever's possible using the 2nd equation. So, for example, you could substitute using $x^2+y^2=100$ in the remaining equation, and the $x^2$ and $y^2$ terms disappear.
