Respuesta :
The quadratic equation may be expressed in a form, ax² + bx + c =0. From the given equation, a = 2, b = 1, and c = -3. Substituting these value to the equation of the discriminant (D).
D = b² - 4ac
D = 1² - (4)(2)(-3) = 25
Thus, the discriminant of the equation of 25.
D = b² - 4ac
D = 1² - (4)(2)(-3) = 25
Thus, the discriminant of the equation of 25.
It is used to determine the nature of roots of quadratic equation. The value of the discriminant is 25
How to calculate the discriminant of an equation?
The formula for calculating the discriminant of a quadratic equation is given as:
D= b^2 - 4ac
It is used to determine the nature of roots of quadratic equation
Given the equation
2x^2 + x - 3 = 0
a =2
b = 1
c = -3
Substitute
D = b^2 - 4ac
D = 1^2 - 4(2)(-3)
D =1 + 25
D = 25
Hence the value of the discriminant is 25
