Question

which of the following is the value of the discriminat for ander root 2x2-5x+2=0?
​

Answer 1

Answer: Discreminant = 17

Explanation:

Compare √2x² -5x +√2 =0

with ax²+bx+c = 0 , we get

a=√2 , b = -5 , c = √2

Discreminant (D) = b²-4ac

= (-5)²-4×√2×√2

= 25 - 4×2

= 25 - 8

= 17

Therefore,

Discreminant = 17
