Find the rational zeros of the polynomial function, f(x)= 4x^3-8x^2-19x-7

The rational zero of the polynomial are  .  

Step-by-step explanation:

Given polynomial as :

f(x) = 4 x³ - 8 x² - 19 x - 7

Now the ration zero can be find as

,

where P is the constant term

And Q is the coefficient of the highest polynomial

So, From given polynomial ,  P = -7 , Q = 4

Now ,

I.e   =

Or, The rational zero are

Hence The rational zero of the polynomial are  .  Answer

x = -2

y = 848
