Question

If a,b are the zeros of the polynomial f(X)=x^+x+1, then Find the value of 1/a+1/b

Answer 1

Answer:

$\frac{1}{a} + \frac{1}{b} = - 1$

Step-by-step explanation:

We know that

Sum of zeroes = a + b = $\frac{-b}{a}$

Product of zeroes = ab = $\frac{c}{a}$

Now we get a + b = -1 and ab = 1

Now ,

$\frac{1}{a} + \frac{1}{b}$

By taking LCM , we get

=$\frac{a + b}{ab}$

= $\frac{- 1 }{1}$

Then we get -1

So your answer for these question is -1 hope these may help you
