How can I find the roots of 2nd order equations ?

To find the roots of a 2nd order equation, the coefficients of the variable in the equation are needed. Using these coefficients, a mathematical value called discriminant is calculated. Discriminant is indicated by the delta symbol. In order for the equation to have real roots, the discriminant value must be greater than or equal to 0. If the discriminant is greater than 0, it means that the equation has two different real roots. If the discriminant is less than 0, the equation has no real root, it has two complex roots that are conjugate to each other. If discriminant is 0, the equation has two coincident roots.
To find the roots, this discriminant value is substituted in the relevant formulas. One of the roots is found by the formula x1 = (- b + root (delta)) / (2a), while the other root is found by the formula x2 = (- b-root (delta)) / (2a).

Do you know how to find the roots of a 2nd order equation ?

To find the roots of a 2nd order equation, the coefficients of the terms that make up the equation are used. With the help of these coefficients, the numerical value of the mathematical expression called discriminant is reached. The numerical values of the roots are obtained by using both the discriminant and the coefficients. Sometimes, the numerical values of the roots can be easily found by factoring the equation. Roots can be real or complex (complex) roots. They may be different from each other or they can be equal to each other. If the roots of the equation are complex, then the roots are conjugates.
