If the discriminant of an equation is zero is true of the equation?
That its roots (solutions) are coincident.
What is true of an equation if its discriminant is zero?
it has one real solution
What is true about a quadratic if the discriminant is negative?
There are two complex solutions.
What type of equation is b2-4ac?
6
How does the discriminant affect the roots of a quadratic equation?
If the discriminant is negative, the roots will be two unreal complex conjugates. If the discriminate is positive the roots will be real.
What do you do if you have a negative discriminant in a quadriatic equation?
By calculating the discriminant of the equation and if it's negative the equation will have no solutions
What kind of solution does an equation has if the discriminant is negative?
If the discriminant is negaitve, there are no "real" solutions. The solutions are "imaginary".
If the discriminant of an equation is zero What is true of the equation?
That its roots (solutions) are coincident.
If the discriminant of an equation is zero is true of the equation?
That its roots (solutions) are coincident.
What does the discriminant tell you?
The discriminant tells you how many solutions there are to an equation The discriminant is b2-4ac For example, two solutions for a equation would mean the discriminant is positive. If it had 1 solution would mean the discriminant is zero If it had no solutions would mean that the discriminant is negative
If the discriminant is negative the equation has solutions?
As stated in the attached link, there are three possible discriminant conditions: Positive, Zero, or Negative. If the discriminant is negative, there are no real solutions but there are two imaginary solutions. So, yes there are solutions if the discriminant is negative. The solutions are imaginary, which is perfectly acceptable as solutions.
If the discriminant of an equation is negative?
It has two complex solutions.
What is true of an equation if its discriminant is zero?
it has one real solution
If the discriminant of a quadratic equation equals zero what is true of the equation?
It has one real solution.
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
If the discriminant is negative the equation has?
No real roots but the roots are a pair of complex conjugates.
What is true about a quadratic if the discriminant is negative?
There are two complex solutions.
