Answer:
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
