$0 \: is \: your \: answer$

Answer 2

If the roots of a quadratic equation are real & equal then the discriminant is zero.

• A quadratic equation is a polynomial with the order of polynomial as 2 which means the highest power of x will be 2.
• The maximum number of roots possible for a quadratic equation is 2.
• The roots of a quadratic equation are defined as the value of x when x gives the value of the equation as 0.
• The discriminant is for an equation ax^2+bx+c is defined as D=b^2-4ac
• When the value of Discriminant becomes 0 then the roots are real and equal.
