ok the problem states find all rational zeros of the function f(x)= 2x^4-15x^3+23x^2+15x-25
there are additional factors for the constant, what are they and how do i go about finding them? i dont want pts taken off from my exam by not finding ALL the factors.
and when i solve this problem, should i use the quadratic function or should i continue using synthetic division until its completely factorized? i got the answer, i just continued using synthetic division, i see that u can also use the quadratic function, question is does it matter what i use?
factors of constant are:+-1,+-5,+-25
factors of coefficient are:+-1,+-2
possible zeros are obtained by dividing the factors of constant by factors of coefficient? and they are,
is there an easier way to obtain the possible zeros when u have alot to divide?
