Question

What is the value of discriminant for a quadratic equation 2x²-3x-4=0

Answer 1

Answer:

D = 41

Step-by-step explanation:

D = b² - 4ac

in given quadratic equation

a= 2, b= -3, c= -4

so, D= (-3)²- 4(2)(-4)

= 9 + 32

= 41

Answer 2

Answer:

Discriminant = 41

Step-by-step explanation:

Discriminant (D) = b² - 4ac

a = 2, b = -3, c = -4

D = (-3)² - 4 x 2 x (-4)

D = 9 + 32

D = 41

Quadratic Equation: An equation whose variable's highest exponent is 2.

The general form of a quadratic equation:

ax² + bx + c = 0

where a, b & c are real numbers and a ≠ 0.

Discriminant of a quadratic equation is given as

D = b² - 4ac

• If D > 0, then two distinct roots
• If D = 0, then two equal roots
• If D < 0, then imaginary roots.
