If there is only one solution one says that it is a double root. A polynomial of degree two is called a quadratic polynomial. A quadratic equation always has two roots if complex roots are included and a double root is counted for two.
This form of representation is called standard form of quadratic equation.
X 02 or 1. A polynomial of degree two is called a quadratic polynomial. This form of representation is called standard form of quadratic equation. A quadratic equation of the form ax2 bx c 0 a 0 where a b c are constants and x is a variable is called a quadratic equation in the standard form.
