How many roots does the quadratic equation have?

two
A quadratic equation with real or complex coefficients has two solutions, called roots.

How do you find the real roots of a quadratic equation?

To calculate the roots of a quadratic equation we use the following formula: where b 2 − 4 a c is called the discriminant. If discriminant > 0, then the equation has two distinct real roots. If discriminant = 0, then the roots of the equation are real and same.

How do you find the standard form of a quadratic equation?

The standard form of a quadratic equation is: ax2 + bx + c = 0, where a, b and c are real numbers and a ≠ 0. The term b2-4ac is known as the discriminant of a quadratic equation. The discriminant tells the nature of the roots.

How to find the discriminant of a quadratic equation?

Take inputs of all coefficient variables x, y and z from the user. Discriminant = (y * y) – (4 * x *z). Calculate the roots based on the nature of the discriminant of the quadratic equation. Print the roots are real and distinct. Root1 = Root2 = -y / (2 * x). Print both roots are real and equal.

How to find the square root of a number using sqrt?

It tells the nature of the roots. If the discriminant is greater than 0, the roots are real and different. If the discriminant is equal to 0, the roots are real and equal. If the discriminant is less than 0, the roots are complex and different. In this program, the sqrt () library function is used to find the square root of a number.
