Question

2y2 - 7y + 2 = 0 find discriminant​

Answer 1

Discriminant= b²-4ac

Where a= 2 ,b= -7 c= 2

so b²-4ac= (-7)²-4(2)(2)

= 49-16

= 33

$\huge\boxed{answer = 33}$

Answer 2

Solution :-

Given :-

2y² - 7y + 2 = 0 is a quadratic equation.

To Find :-

The discriminant of this equation.

→ Discriminant :- The discriminant is a part of the quadratic formula under the square root.

So, by comparing the equation with ax² + bx + c

• a = 2

• b = -7

• c = 2

Discriminant (D) = b² - 4ac

D = (-7)² - 4 × 2 × 2

D = 49 - 16

$\boxed{D = 33}$
