Question

Write the discriminant of the following quadratic equations:

2x² - 5x + 3 = 0

Answer 1

We have been given, 2x² - 5x + 3 = 0

Now we also know that for an equation , the ax² + bx + c = 0 discriminant is given by the following equation:

D = b² - 4ac

Now, according to the equation given to us, we have, a = 2, b = -5 and c = 3.

Therefore, the discriminant is given as,

D = (-)² - 4(2)(3)

= 25 - 24

= 1

Therefore, the discriminant of the equation is 1.
