# Find the Value of Discriminant. 2y2 – 5y + 10 = 0 - Algebra

Find the value of discriminant.

2y2 – 5y + 10 = 0

#### Solution

2y2 – 5y + 10 = 0 Comparing the given equation with $a x^2 + bx + c = 0$

$a = 2, b = - 5 \text{ and } c = 10$ So, the discriminant $b^2 - 4ac = \left( - 5 \right)^2 - 4 \times 2 \times 10 = 25 - 80 = - 55$
