A Quadratic Equation is usually written ax2 + bx + c = 0, where x is an unknown variable and a,b,c are numerical coefficients Here, a ≠ 0 because if it equals to zero then the equation will not remain quadratic anymore and it will become a linear equation, such as bx+c=0.
where ± (one plus and one minus) represent two distinct roots of the given equation.
Quadratic Equation Definition
The polynomial equation whose highest degree is two, is called a quadratic equation. It is expressed in the form of:
ax² + bx + c = 0
where x is the unknown variable and a, b and c are the constant terms.
