Understanding Bhaskara's Formula

What is the formula for Bhaskara?

• x = (b ± √(b² + 4ac)) / (2a)

• x = (b ± √(b² - 4ac)) / a

• x = (-b ± 4√(b² - ac)) / (2a)

• x = (-b ± √(b² - 4ac)) / (2a)

If a = 1, b = -3, c = 2, what are the roots?

• [-1, 4]

• [2, 1]

• [0, 3]

• [1, -2]

How do you calculate the discriminant in Bhaskara's formula?

• D = 4b - ac

• D = b^2 - 4ac

• D = 2b + 4ac

• D = a^2 + b^2 + c^2

What does the discriminant tell us about the roots?

• The discriminant indicates the sum of the roots.

• The discriminant shows the coefficients of the equation.

• The discriminant tells us the nature of the roots of a quadratic equation.

• The discriminant provides the exact values of the roots.

Can Bhaskara's formula be used for any quadratic equation?

• Yes, Bhaskara's formula can be used for any quadratic equation.

• Yes, but only for equations with real coefficients.

• No, Bhaskara's formula only works for specific types of quadratic equations.

• No, it can only be used for equations with integer solutions.
