You can put this solution on YOUR website!
You already posted the same question to which I gave my response.

Note that a root (also called a zero) of a polynomial function is ALSO one of its solutions. This means that an x-axis intercept of a polynomial function is a solution.

You can find the y-axis intercept by setting x=0 and evaluate the function.

(REMINDER: Your factorization which you later gave is correct.)
