Question

If a and b are zeroes of the quadratic polynomial x2+x-2, then the value of 1/a +1/b=

Answer 1

Step-by-step explanation:

If α and β are the zeroes of a quadratic

polynomial x2 + x – 2 then find the value of

(i) 1/ α + 1/ β

★

If α and β are the zeroes of a quadratic polynomial x²+ x – 2.

x²+x-2=0.....................(i)

•• Compare (i) no. equation with ax²+bx+c = 0.

So,

a = 1

b= 1

c=(-2)
