Khan Academy The discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac The discriminant tells us whether there are two solutions, one solution, or no solutions
Solving quadratic equations | Lesson (article) | Khan Academy Quadratic equations without x -terms such as 2 x 2 = 32 can be solved without setting a quadratic expression equal to 0 Instead, we can isolate x 2 and use the square root operation to solve for x When solving quadratic equations by taking square roots, both the positive and negative square roots are solutions to the equation
Discriminant for types of solutions for a quadratic Use the discriminant to state the number and type of solutions for the equation negative 3x squared plus 5x minus 4 is equal to 0 And so just as a reminder, you're probably wondering what is the discriminant And we can just review it by looking at the quadratic formula So if I have a quadratic equation in standard form, ax squared plus bx plus c is equal to 0, we know that the quadratic
