how can I find all the zeros of f(x)=x^4-9x^2-22x-24 I have watched your factoring videos but they dont seem to work. I know I cant do the quadratic formula and I tried grouping but it doesnt work. Am I doing it wrong?
+PinkPrincess1177 yes a polynomial to the 4th power, you cannot use the quadratic formula, this one cannot be factored so I would graph it to determine a rational zero then use synthetic division to further divide the polynomial. I have videos labeled find all of the zeros using synthetic division, hopefully they will help you out, let me know
Why we didn’t calculate intercepts
Not sure, I should have included that as a step
