What is true about a quadratic if the discriminant is negative?
There are two complex solutions.
What is true of an equation if its discriminant is zero?
it has one real solution
If the discriminant of an equation is zero is true of the equation?
That its roots (solutions) are coincident.
What is true of the discriminant when the two real number solutions to a quadratic equation are rational numbers?
The discriminant must be a perfect square or a square of a rational number.
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

What do you mean if a linear model underestimates?
In graph form, the linear equation lies below the true line or curve.
Is it true a straight diagonal line on a distance versus time graph indicates constant speed?
The answer is TRUE because it is a straight line as the graph shows below. http://www.batesville.k12.in.us/physics/apphynet/Measurement/Images/d_vs_t2_graph.gif

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
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
If the discriminant of a quadratic equation equals zero what is true of the equation?
It has one real solution.
