Question

Find the value of discriminant. 2y2 − 5y + 7 = 0​

Answer 1

Answer:

here a=2b=-5andc=7

D=√b^2-4ac

=√-5^2-4×2×7

=√25-56

=√-31

Answer 2

SOLUTION

TO DETERMINE

The value of discriminant

2y² - 5y + 7 = 0

EVALUATION

Here the given Quadratic equation is

2y² - 5y + 7 = 0

Comparing with the general equation

ay² + by + c = 0 we get

a = 2 , b = - 5 , c = 7

Hence the required value of the Discriminant

= D

= b² - 4ac

$\sf{ = {( - 5)}^{2} - 4 \times 2 \times 7}$

$\sf{ = 25 - 56}$

$\sf{ = - 31}$
