9x2 - 12x + 4 = 0 is of the form ax2 + bx + c = 0 where the discriminant, D, can be found by

D = b2 - 4ac

First, you find the values of a, b and c:

a = 9

b = -12

c = 4

Now you can find D:

D = (-12)2 - (4)(9) = 144 - 36 = 108

D = 108

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

In the quadratic equation ax2 plus bx plus c 0 if b2 - 4ac?

If you mean b^2 -4ac then it is the discriminant of a quadratic equation. If the discriminant equals 0 then the equation has 2 equal roots. If the discriminant is greater than 0 then the equation has 2 different roots. If the discriminant is less than 0 then it has no real roots.

What is the answer to the discriminant equation of -4.9 plus 4.3t plus 10?

A discriminant is based on the differences between roots of an equation. A linear equation, such as the onle in the question, has only one root and therefore cannot have a discriminant.


What is x2 plus 5x plus 9 equals 0?

It has no solutions because the discriminant of the quadratic equation is less than zero.
