Without solving, examine the nature of roots of the equations 2x2 – 5x + 5 = 0
Step 1:- For, 2x2 – 5x + 5 = 0, value of discriminant D = (−5)2 – 4 ( 2) (5) = 25 -40 = -15 ˂0 .
Step 2:- Since, D ˂0, roots of the quadratic equation are imaginary.
Without solving , examine the nature of roots of the following quadratic equations:
