You have to find one root, then use long division to factor the polynomial.
can u please show me how? idk how to find it :(

Are you allowed to use a scientific calculator in your exams?
yes I'm allowed to :) this is a practice worksheet and i need to show my work :/ and idk how to solve much less show work lol :/
do u understand how to solve this? cuz i am lost :(
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)^3-119(8)^2-10(8)+16=0
Now, x=8, (x-8) 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 :)
You are dividing (x-8)
Because x=8 for the f(x) is zero
okay, so I'm dividing 15x^3-119x^2-10x+16 divided by x-8?
Yes
k i got 15x^2+x-2... so is that my answer?? :)
@.Sam. is that my answer???
yes
kk thanks! :)
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+x-2
Use factor or quadratic equation or completing the square to solve 15x^2+x-2
kk thanks!! :)
welcome
