Question

find the discremenent of quadratic equation x2-4x+2​

Answer 1

Question:

find the discremenent of quadratic equation x² - 4x + 2.

Solution:

We have,

x² - 4x + 2 = 0

• Comparing the equation with ax²+bx+c=0, We infer:

1. a =1
2. b = -4
3. c =2

Applying the Discriminant, D:

b²-4ac

→ (-4)²- 4(1)(2)

→ 16-8

→ 8

Hence,

The Discriminant = 8
