Question

if a and b are the zeros of the quadratic polynomial f(x) =5y2 -7y+1 find the value of 1/a+1/b​

Answer 1

Answer:

7

Step-by-step explanation:

Since the roots are a and b,

we know that,

a+b = (-b/a) = (-(-7)/5)=(7/5)

and ab = c/a = (1/5).

So, (1/a)+(1/b)=(a+b)/(ab)

=(7/5)/(1/5)=7/1=7

The answer to your question is 7.
