Determine whether the given quadratic equation has root(s). If so, findthe root(s). y 2+https://static.philoid.co/ncertusercontent/solutions/user_files/63094/15042/images/extra-4_files/Image1216.gif y – 1  =0.


a = 1, b = and c = -1
Δ = b 2 – 4ac

= ( ) 2 – 4(1)(-1)

=

Therefore the quadratic equation has real roots.
