Question

find all of the rational zeros of the function: f(x)= 2x^3+14x^2+24x.....can someone show me how to do this, i need to understand it

Answer 1

well you can factor as a first step to get
\[x(2x^2+14x+24)\] as a start. so one zero is at 0. the other two you can find using the quadratic formula

Answer 2

i guess i could have been smarter and factored as
\[2x(x^2+7x+12)\]
then factor to get
\[2x(x+3)(x+4)\] and so zeros area at 0, -3, -4

Answer 3

thank you a lot :)
