Question

Find the zeroes of the following quadratic polynomial and verify the relation between the zeroes and coefficient.
a)4s2-4s+1

Answer 1

Answer:

4s^2-4s+1

=4s^2-2s-2s+1

=2s(2s-1)-1(2s-)

=(2s-1)(2s-1)

therefore,

2s-1=0. or. 2s-1=0

=>s=1/2. =>s=1/2

zeroes are 1/2 and 1/2

now,

1/2+1/2=2/2

=1

=-(-4)/4

=-b/a

1/2×1/2=1/4

=c/a
