In the case of real roots, you could, but the second part of the ordered pair (the ordinate) will always be zero, so there is not much point.

In the case of complex roots (or real roots in the complex field), you could list them as ordered pairs: with (a, b) representing a + bi where i is the imaginary square root of -1..

What are quadratic equations with real roots?

If the discriminant of the quadratic equation is zero then it will have 2 equal roots. If the discriminant of the quadratic equation is greater than zero then it will have 2 different roots. If the discriminant of the quadratic equation is less than zero then it will have no roots.


What are the roots of a quadratic?

The roots of a quadratic function are where the lies interescts with the x-axis. There can be as little as zero.


Why do you use square roots to solve quadratic equations?

Because it's part of the quadratic equation formula in finding the roots of a quadratic equation.


How many roots does a quadratic equation?

2 roots


What are the roots of the quadratic equation below?

That depends on the equation.


How many roots can a quadratic function have?

The answer is two. Despite its name seems to suggest something to do with four, in a quadratic equation the unknown appears at most to the power of two and so is said to be of second degree. The theorem than pertains here is that the number of roots an equation has is equal to its degrees. However, some of the roots can be repeated - an nth degree equation need not have n different roots. Also the roots do not have to be real. However complex roots ( no real) come in pairs so an equation of odd degree must have at least one real root. A quadratic possibly has no real roots.


What is the graph of a quadratic formula?

In general, quadratic equations have graphs that are parabolas. The quadratic formula tells us how to find the roots of a quadratic equations. If those roots are real, they are the x intercepts of the parabola.


Can the answer to a quadratic equation be a decimal?

Yes. You can calculate the two roots of a quadratic equation by using the quadratic formula, and because there are square roots on the quadratic formula, and if the radicand is not a perfect square, so the answer to that equation has decimal.


What are the roots of a quadratic equation called?

Either "roots" or "solutions".


What is the formula to find the product of the roots of a quadratic equation?

If the quadratic is ax2 + bx + c = 0 then the product of the roots is c/a.


Why do mathmaticians use the quadratic formula?

To find the roots (solutions) of a quadratic equation.


How is solving a quadratic equation the same as finding its roots?

That is what roots mean!
