Question

Find The Discriminant of the quadratic equation 36x^2-12ax+(a^2-b^2)=0​

Answer 1

Equation:

==> 36x² - 12ax + ( a² - b² ) = 0

On comparing,

==> a = 36

==> b = -12a

==> c = (a² - b²)

Discriminant,D = b² - 4ac

==> D = (-12a)² - 4 × 36 × (a² - b²)

==> D = 144a² - 144a² + 144b²

==> D = 144b²
