How many solutions discriminant
Web13 okt. 2024 · The discriminant is the term underneath the square root in the quadratic formula and tells us the number of solutions to a quadratic equation. If the discriminant is positive, we know that we have 2 solutions. If it is negative, there are no solutions and if the discriminant is equal to zero, we have one solution. WebAnswer: A positive discriminant denotes that the quadratic has two different real number solutions. A discriminant of zero denotes that the quadratic consists of a repeated real number solution. A negative …

Web8 okt. 2024 · Starting from the equation of a quadratic in standard from; ax 2 +bx+c = 0, the discriminant is b 2 – 4ac. Because this is the argument to a square root operation, we can make some inferences. If b 2 – 4ac > 0. i.e. the discriminant is a positive number, then the quadratic will have two real solutions. The graph will cross the x-axis in two ... cool water shores lake gogebicWebThis 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.
