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 ax^2 + bx + c = 0, where a, b and c are real numbers and a is non-zero, the discriminant is b^2 – 4ac.

What is the value of the discriminant of the polynomial 3x²-7x plus 4?
72-4*3*4 = 1
What is the value of the discriminant polynomial 3x2 plus 6x plus 5?
b^2 - 4ac Is the discriminant. 6^2 - 4(3)(5) 36 - 60 = - 24 < 0 so, an unreal answer and no real X intercepts
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
What is the value of the discriminant of the polynomial 3x2-7x 4?
The discriminant, ( first positive 4 in the constant, then negative 4 as you did not specify this ) b2 - 4ac ------------ (- 7)2 - 4(3)(4) 49 - 48 = 1 ============a positive number means two real roots ( - 4 now ) ( - 7)2 - 4(3)(- 4) 49 + 48 = 97 ============still positive and two real roots
What is the value of the discriminant for the quadratic equation 2a2 7a 3 0?
The discriminant is b^2-4ac. So, b=7, a=2, and c=3. 7^2=49-4(2)(3)=49-24=25. So the discriminant is 25.
What is the value of the discriminant of the polynomial 3x2-7x plus 4?
49-(4*3*4) = 1
What is the value of the discriminant of the polynomial 3x²-7x plus 4?
72-4*3*4 = 1
What is the value of the discriminant polynomial 3x2 plus 6x plus 5?
b^2 - 4ac Is the discriminant. 6^2 - 4(3)(5) 36 - 60 = - 24 < 0 so, an unreal answer and no real X intercepts
What is the discriminant of the polynomial below x2 plus 5x plus 7?
52-4*7*1 = -3 The discriminant is less than zero so the quadratic equation will have no solutions.
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
What is the value of the discriminant of the polynomial 3x2-7x 4?
The discriminant, ( first positive 4 in the constant, then negative 4 as you did not specify this ) b2 - 4ac ------------ (- 7)2 - 4(3)(4) 49 - 48 = 1 ============a positive number means two real roots ( - 4 now ) ( - 7)2 - 4(3)(- 4) 49 + 48 = 97 ============still positive and two real roots
What is the value of the discriminant for the quadratic equation 2a2 7a 3 0?
The discriminant is b^2-4ac. So, b=7, a=2, and c=3. 7^2=49-4(2)(3)=49-24=25. So the discriminant is 25.
Which best describes a root of a polynomial?
A "root" of a polynomial is any value which, when replaced for the variable, results in the polynomial evaluating to zero. For example, in the polynomial x2 - 9, if you replace "x" by 3, or by -3, the resulting expression is equal to zero.
2x2 - 10x plus 3 What is the value of the discriminant of the polynomial?
Let P(x) = 2x2 - 10x + 3. Let P(x) = 0, then2x2 - 10x + 3 = 0 (a quadratic equation, where a = 2, b = -10, and c = 3)D = b2 - 4ac = (-10)2 - 4(2)(3) = 100 - 24 = 76
What is the value of the discriminant of the polynomial -3x2-4x 1?
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals", "squared", "cubed" etc. The sign for the constant term is missing! Assuming it is meant to be a + the discriminant = (-4)2 - 4*(-3)*(1) = 16 + 12 = 28
A quadratic polynomial is a third-degree polynomial?
No. A quadratic polynomial is degree 2 (2 is the highest power); a cubic polynomial is degree 3 (3 is the highest power).No. A quadratic polynomial is degree 2 (2 is the highest power); a cubic polynomial is degree 3 (3 is the highest power).No. A quadratic polynomial is degree 2 (2 is the highest power); a cubic polynomial is degree 3 (3 is the highest power).No. A quadratic polynomial is degree 2 (2 is the highest power); a cubic polynomial is degree 3 (3 is the highest power).
What are 3 outcomes for the discriminant?
If the discriminant of a quadratic equation is zero then it has equal roots. If the discriminant is greater than zero then there are two different roots. If the discriminant is less than zero then there are no real roots.
