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
Use the quadratic equation y equals x2 plus 3x plus 9 Calculate the discriminant to determine the number of real roots?
The discriminant is -27 and so there are no real roots.
What Greek letters stand for the discriminant of the quadratic formula?
The Classical Greek letter for the discriminant is 'Delta' , which is shaped like a triangle with the left side being a vetrtical line and standing on a corner of the triangle. However, 'D' or 'd' is often used in maths.
How do you use the discriminant to find the number and type of zeros of a function?
If the discriminant is positive, then the function has two real zeros. If it is zero, then the function has one real zero. If it is negative, then it has two complex conjugate zeros.This assumes that we are talking about a standard second order polynomial equation, i.e. quadratic equation, in the form Ax2 + Bx + C = 0, and that the discriminant is B2 - 4AC, which is a part of the standard solution of these kind of equations.
Is there a job or profession that does not use math?
Possibly a hermit or ascetic.
