correct factors
(x-3)(x+2)(x+4).
I found that (x-3) is a factor
Then you use synthetic division x^3+3x^2-10x-24 by x-3 x^2+6x+8 factor the trinomial
=(x-3)(x+2)(x+4)
2.
We can use remainder theorem, which basically is when f(x) is a polynomial in x then the remainder on dividing f(x) by x − a is f(a). to show the binomial is a factor of g(x): using long division with (x+2) as the divisor
Then using synthetic division with -2 as the three people were correct. Though Mr. Romano was half wrong because he would really need to use -2 as the divisor using synthetic division.
3.
First we have to find the x-intercepts by using the rational root theorem
Then we have to find the y-intercepts, we do this by replacing the
