You have to find one root, then use long division to factor the polynomial.

I would use trial an error from calculator, you key the equation into your calculator, then substitute any number for x and see if its equal to zero, if that value of x equals to zero, then that is the factor of the polynomial

Ok, according to the trial an error, x=8 works, so, f(8)=15(8)^3119(8)^210(8)+16=0

Now, x=8, (x8) is a factor of that polynomial. then use this to find other factors, by long division.

so, what exactly am i dividing?? and can you please type or draw out all the work in order?? :) i understand better that way :)

.Sam.Best ResponseYou've already chosen the best response.1
Because x=8 for the f(x) is zero

okay, so I'm dividing 15x^3119x^210x+16 divided by x8?

k i got 15x^2+x2... so is that my answer?? :)

can u pls help me with another one>? :)

But if they tell you to solve, that means you have to find x from 15x^2+x2

.Sam.Best ResponseYou've already chosen the best response.1
Use factor or quadratic equation or completing the square to solve 15x^2+x2
