Q25 of 109 Page 3

If a – b, a and a + b are zeros of the polynomial f (x) = 2x3 – 6x2 + 5x – 7, write the value of a.

Given;


A polynomial f(x) = 2x3 – 6x2 + 5x – 7


And zeroes are a – b, a and a + b,


Let’s take a = α


b = β


c = y


As we know that,


α + β + y = – b/a


(a – b) + a + (a + b) = – ( – 6)/2


3a = 3


a = 1


So, the value of a = 1
