Yes, but only if you count a root at the tangent as a double root.

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.

What is a number that has more than two square roots?

There is no number that has more than two square roots.By definition, the "square" bit implies two.Every number has exactly:TWO square roots,THREE cube roots,FOUR quadratic roots,etc.

What does the discriminant have to be in order for the roots of a quadratic to be irrational?

The discriminant must be a positive number which is not a perfect square.

What are the roots of a quadratic equation called?

Either "roots" or "solutions".

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.

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.
