Question

4) Which of the following is the value of discriminant for the quadratic equation

\sqrt { 2 } x ^ { 2 } - 5 x + \sqrt { 2 } = 0 ?​

Answer 1

Answer:

Discriminant, in mathematics, a parameter of an object or system calculated as an aid to its classification or solution. In the case of a quadratic equation ax² + bx + c = 0, the discriminant is b² − 4ac; for a cubic equation x³ + ax² + bx + c = 0, the discriminant is a²b² + 18abc − 4b³ − 4a³c − 27c².
