Question

the nature of root of quadritic equation 2x2-2x+1=0

Answer 1

the formula is b^2 - 4 a c

a = 2

b =2

c= 1

2^2 - 4 *2*1

4-8= -4

therefore the nature is no real roots

Answer 2

here,
a=2, b=-2 , c=1
therefore,
b^2-4.a.c
=(-2)^2 - 4 . 2. 1
=4 - 8
=-4
since, b^2-4ac< 0
therefore, the roots are not real
