![]() We discovered (derived) the simplest such formula and said: 'It's so useful it deserves a name, let it be discriminant. The discriminant reveals the number of real solutions because: it's useful to know the number of real solutions and at least one formula (function of $a$, $b$ and $c$) that leads to this number does exist. Why does the discriminant in the Quadratic Formula reveal the number …. Solving Quadratic Equations using the QUADRATIC FORMULA X = If using algebra and square roots, or factoring and ZPP don't work, you can ALWAYS find solutions to . How can you find out how many solutions an equation has? Use the discriminant to find the number of solutions - SlidePlayer. If the discriminant is less than 0, the quadratic equation has 0 real solutions. To find the discriminant given the quadratic equation f (x)=ax^2+bx+c, simply record the values of a, b, and c and then substitute them into the discriminant … how many solutions are there to the equation below. What is the Discriminant? | How to Find the Discriminant. If b2 – 4ac simplifies into a positive number .The value of the discriminant tells you whether the quadratic has 2 solutions, 1 solution, or no real solutions. ![]() Discriminant - Academic Support Center - Google Sites. ![]()
