Question

find the value of the discriminat for the quadratic equation 2y²-5y+20=0​

Answer 1

Given :

• ➻ 2y² - 5y + 20 = 0

Find :

• ➻ Find the value of the discriminant for the quadratic equation.

Solution :

• ➻ Comparing the given equation with ax² + bx + c = 0.

Now, we get :

• ➮ a = 2
• ➮ b = -5
• ➮ c = 10

• So, the discriminant : b² − 4ac

Hence,

• ➢ (−5)² − 4 × 2 × 10

• ➢ 25 − 80

• ➢ −55

❖Therefore,

• The value of the discriminant for the quadratic equation is −55.
