Determine whether the given quadratic equation has root(s). If so, findthe root(s):2x 2+ 5https://static.philoid.co/ncertusercontent/solutions/user_files/63094/15042/images/extra-4_files/Image1256.gif + 16 =0.


a = 2,

and

c = 16
Δ = b 2 – 4ac

Δ  = 75 – 128

Δ  = – 53
Therefore the quadratic equation has no real roots.
