Question

Find Discriminate of quadratic equation 4x^2-ax+2=0

Answer 1

Discriminat= b^2-4ac

here a=4 b=-a c=2.

(-a)^2-4(4)(2)

a^2-32

is your answer

Answer 2

Answer:

$\implies$ 4x² - ax + 2 = 0

We know that:

Discriminant ( D ) = b² - 4ac

$\implies$ D = (-a)² - 4.4.2

$\implies$ D = a² - 32

Hence:

A takes the value of a² - 32.
