What statements must be true of an equation before you can use the quadratic formula to find the solutions?

That the discriminant of the quadratic equation must be greater or equal to zero for it to have solutions. If the discriminant is less than zero then the quadratic equation will have no solutions.


What is true about a quadratic equation when the discriminant of the equation is positive?

It will then have 2 different roots If the discriminant is zero than it will have have 2 equal roots


Which values for a b or c can you not use the quadratic equation?

a = 0. That is because a = 0 implies that there is no quadratic term and so the equation is not a quadratic!There may be some who make claims depending on the value of the discriminant (which is b2-4ac). That is true only for elementary mathematics. In more advanced mathematics (complex analysis), the quadratic equation can be used in all cases except when a = 0: the value of the discriminant is irrelevant.a = 0.

What is true of the discriminant?

It discriminates between the conditions in which a quadratic equation has 0, 1 or 2 real roots.





What is the solving for the roots of quadratic equation?

It is finding the values of the variable that make the quadratic equation true.





What is the solution of the quadratic equation 2y plus y equals -11y?

This equation is not quadratic it is linear.The only situation where this equation could hold true is if y is equal to 0.2y + y = -11y3y = -11y3y + 11y = 014y = 0y = 0


What is a root of a quadratic equation?

The root of any equation is a number which ... when substituted for the variable ...makes the equation a true statement.


Is it true that discriminant can hold all the quadratic function?

I dont even know my times tables yet!! im only 4




What has no true roots?

An equation with a discriminant that is less than zero. Note that in getting the discriminant, use the general form: ax²+bx+c=0 D=b²-4ac


A quadratic polynomial has a degree of 2?

True Yes. Although the term 'quad' stands for four, a quadratic equation is a polynomial of second degree.


What statement must be true of an equation before you can use the quadratic formula to find the solutions?

The quadratic formula can be used to find the solutions of a quadratic equation - not a linear or cubic, or non-polynomial equation. The quadratic formula will always provide the solutions to a quadratic equation - whether the solutions are rational, real or complex numbers.


What are you finding when you solve a quadratic equation?

You are finding the roots or solutions. These are the values of the variable such that the quadratic equation is true. In graphical form, they are the values of the x-coordinates where the graph intersects the x-axis.


Is 10 equals 120 an expression or an equation?

If a statement includes an "equals" sign ( = ) then the statement is an equation. By the way . . . it may or may not be a true statement. "10 equals 120" is not true.



Why would one use a quadratic equation?

One true purpose for which you could use a quadratic equation could be to figure the maximum use of crop planting in a field once you have the true area of the field figured. Quadratic equations can also be used to figure the area or the volume or the capacity of any unusually shaped object.
