Q8 of 113 Page 50

Find the zeros of the following quadratic polynomials and verify the relationship between the zeros and the coefficients:

4x2 – 4x + 1

Let f(x) =4x2 – 4x + 1 8x

Put f(x) = 0


4x2 - 4x + 1 = 0


(2x)2 – 2(2x)(1) + (1)2 = 0


(2x - 1)2 = 0



Now,


sum of zeroes


Product of zeroes


Hence, relationship verified.
