The browser that is used for submitting questions does not permit many mathematical symbols. It is therefore not possible to be sure what the question was. For a quadratic equation of the form y = ax^2 + bx + c, where a, b and c are real numbers and a is non-zero, the discriminant is b^2 – 4ac.
Note that the equation must first be written with descending powers of x so as to identify a, b and c.

What is the discriminant of the polynomial 9x2 - 18x 9?
The discriminant is 0.
What is 9x2 equals 10x plus 2?
It is a quadratic equation and its solutions can be found by using the quadratic equation formula.
Is 9x2-36x 16 a perfect square trinomial?
If you mean: 9x2-36x+16 then it is not a perfect square because its discriminant is greater than zero
Using the discriminant how many times does the graph of this equation cross the x-axis 5x squared -10x-2 equals 0?
Discriminant = (-10)2 - 4*5*(-2) = 100 + 40 > 0 So the quadratic has two real roots ie it crosses the x-axis twice.
Can you solve by completing the square x2 plus 10x plus 220?
No because the discriminant of the given quadratic expression is less than zero.
What is the discriminant of the polynomial 9x2 - 18x 9?
The discriminant is 0.
9x2-18x plus 9 equals 0 what is the discriminant?
The discriminant is 0.
What is the value of the discriminant in 2x2-10x plus 3?
2x2 + 10x - 3 The discriminant is defined as b2 - 4ac, so for this function b=10, a=2, and c=-3 So the discriminant is 100-4*2*-3 = 124
-20xto power of 2 plus 10x plus 10 equals 0 what is the value of discriminant?
The discriminant is 900.
What is the value of the discriminant of -9x2 plus 6x plus 14 equals 0?
The discriminant of a quadratic ax2 + bx + c is b2 - 4ac; thus: the discriminant of -9x2 + 6x + 14 is 62 - 4 x -9 x 14 = 540
What is the discriminant of the polynomial 9x2-18x plus 9?
It is: 0
What is 9x2 equals 10x plus 2?
It is a quadratic equation and its solutions can be found by using the quadratic equation formula.
9x2 plus 2x plus 5-5x2 plus 8x-6?
It is 4x^2 + 10x - 1
How do you factor 9xsquared-28x plus 20?
9x2 - 28x + 20 = 9x2 - 18x - 10x + 20 = 9x(x - 2) - 10(x - 2) = (9x - 10)*(x - 2)
Is 9x2-36x 16 a perfect square trinomial?
If you mean: 9x2-36x+16 then it is not a perfect square because its discriminant is greater than zero
What is the value of k when x2 plus 2kx plus 10x plus k2 plus 5 equals 0 has equal roots?
Equation: x^2 +2kx +10x +k^2 +5 = 0 Using the discriminant: (2k +10)^2 -4*1*(k^2 +5) = 0 Solving the discriminant: k = -2
What is the discriminant polynomial to 9x2-18x plus 9?
It is zero because: 182-4*9*9 = 0
