Web15 apr. 2024 · The discriminant identifies the number and type of solutions to any quadratic equation. The discriminant is the part of the quadratic formula ((-b±√(b 2-4ac))÷2a where ax 2 + bx + c = 0) under the square root: So the value of b 2-4ac determines how many and what type of solutions there are to any quadratic equation.. If b 2-4ac = …
WebThis is the key to knowing how many solutions we have: If b2 - 4 ac is positive (>0) then we have 2 solutions. If b2 - 4 ac is 0 then we have only one solution as the formula is reduced to x = [- b ± 0]/2 a. So x = -b/2 a, giving only one solution. Lastly, if b2 - 4 ac is less than 0 we have no solutions.
