Q54 of 134 Page 4


Determine whether the given quadratic equation has root(s). If so, findthe root(s). y 2– 6y+2=0.


a = 1, b = –6 and c = 2
Δ = b 2 – 4ac

= (–6) 2 – 4(1)(2)

= 36 – 8

= 28
Therefore the quadratic equation has real roots.

α=3-√7

β=3 + √7
Therefore the roots are 3 + √7 and 3 – √7.
