When a b and c are real numbers a 0 and the discriminant is positive then the roots a and v of the quadratic equation ax 2 bx c 0 are real and unequal. If youre solving quadratic equations knowing the quadratic formula is a MUST. First we bring the equation to the form ax²bxc0 where a b and c are coefficients.
Substitute the coefficients from the equation into the formula b2-4acOnce the quadratic equation is in standard form.
Enter the coefficient values such as a b and c in the given input fields Step 2. How Do You Find the Discriminant of a Quadratic Equation. X x 2 4 x2 2 x 4. Three cases are possible.
