q If the quadratic equation is satisfied by more than two numbers (real or complex), then it becomes an identity i.e. a = b = c = 0. q Let a and b be two roots of the given quadratic equation. Then a + b = –b/a and ab = c/a. A quadratic equation, whose roots are a and b can be written as (x – a) The quadratic equation is y=ax^2 +bx +c. So, you substitute in the values of a, b, and c to the quadratic formula (x= -b +/- \|b^2-4ac all over 2a) in order to find the x value then, substitute in ... The quadratic equation is given by the equation ax 2 + bx + c = 0, where x is the variable to be solved for and a, b, and c are coefficients that do not depend on x. The solution to the quadratic equation is known as its roots and can be evaluated by . The roots of the quadratic equation are real numbers only when b 2-4ac is positive or zero.
