Question

3. If a and B are the zeros of the polynomial f(x) = 5x2 – 7x +1, find the
value of
(@/b+B/@)​

Answer 1

Answer:

The value of (a/b+b/b)=7

Step-by-step explanation:

Given :if a and b are the zeros of polynomial

f(x): 5

$f{x} : {5}^{2} - 7x + 1$

we have to find the value of 1/a+1/b

f (x) is equal to 5 x square - 7 x + 1

sum of zeros = a + b = -b/a=7/5

product of zeros = abc=c/a=1/5

Now,

=> 1/a +1/b

=>b+a/ab

=>7/5 / 1/5 = 7

The value of (1/a+1/b)=7
