What is the Quadratic Formula?

Back

The Quadratic Formula is used to find the solutions of a quadratic equation and is given by: x = (-b ± √(b² - 4ac)) / (2a).

FLASHCARD QUESTION

Front

What is the Discriminant in a quadratic equation?

Back

The Discriminant is the part of the quadratic formula under the square root, given by b² - 4ac. It determines the nature of the roots.

FLASHCARD QUESTION

Front

What does a positive Discriminant indicate?

Back

A positive Discriminant indicates that there are two distinct real solutions to the quadratic equation.

4.

FLASHCARD QUESTION

Front

What does a negative Discriminant indicate?

Back

A negative Discriminant indicates that there are no real solutions, only complex solutions.

5.

FLASHCARD QUESTION

Front

What does a Discriminant of zero indicate?

Back

A Discriminant of zero indicates that there is exactly one real solution, also known as a repeated or double root.

6.

FLASHCARD QUESTION

Front

How do you calculate the Discriminant?

Back

The Discriminant is calculated using the formula: D = b² - 4ac, where a, b, and c are the coefficients of the quadratic equation ax² + bx + c = 0.
