Question

What is quadratic equation?​

Answer 1

Answer:

When in a polynomial the degree is 2 is said to be as quadratic equation.

Answer 2

Step-by-step explanation:

Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = ax2 + bx + c where a, b, c, ∈ R and a ≠ 0. It is the general form of a quadratic equation where ‘a’ is called the leading coefficient and ‘c’ is called the absolute term of f (x). The values of x satisfying the quadratic equation are the roots of the quadratic equation (α,β).

The quadratic equation will always have two roots. The nature of roots may be either real or imaginary.

A quadratic polynomial, when equated to zero, becomes a quadratic equation. The values of x satisfying the equation are called the roots of the quadratic equation.

General from: ax2 + bx + c = 0

Examples: 3x2 + x + 5 = 0, -x2 + 7x + 5 = 0, x2 + x = 0.
