Question

Find the zeroes of x^2+x+1

Answer 1

Step-by-step explanation:

Hey there!

________________

f (x) = x^2 + x + 1

Where, a = 1 , b = 1 , c =1

One zero = a

Second zero = b

Sum of zeroes ( a + b ) = - b/a = -1 / 1 = -1

Product of zeroes ( a × b ) = c/a = 1 / 1 = 1

We have to find value of , 1 / a + 1 / b

Taking LCM

= a + b / ab

Keeping the values now,

= -1 / 1

= -1

Thus, 1 / a + 1 / b = -1
