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.
What else can I help you with?
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 4x2 6x-5?

What value for x makes the following equation TRUE 6x 5 equals 31?
That depends on what you mean by "6x 5", which could be 6x * 5, 6x + 5, 6x - 5, 6x / 5, 6x5, etc.
-4x2 plus 6x plus 40 equals 0?
-4x2 + 6x + 40 = 0 ∴ -2x2 + 3x + 20 = 0 ∴ -2x2 - 8x + 5x + 20 = 0 ∴ -2x(x + 4) + 5(x + 4) = 0 ∴ (5 - 2x)(x + 4) = 0 ∴ x ∈ {5/2, -4}
What is -6x-5 plus -10?
-6x - 5 + 10It's an algebraic expression in 'x'. It can be simplifiedby combining like terms:-6x + 5Its numerical value depends on the value of 'x'.
What is the discriminant value in 3x2 6x 5?
The operator (+ or -) before the 5 (and before the 6, but that doesn't matter for the discriminant) is missing from the question, so:If it is 3x2 ± 6x + 5, thendiscriminant = (±6)2 - 4 x 3 x 5 = 36 - 60 = -24 If it is 3x2 ± 6x - 5, thendiscriminant = (±6)2 - 4 x 3 x (-5) = 36 + 60 = 96

What is the degree of 6x5-4x2 plus 2x3-3 plus x?
(6x^5-4x^2)+(2x^3-3) = 6x^5-4x^2+2x^3-3 The grestest exponent is 5, which is the degree of the above expression.
Y equals 4x2 plus 6x - 1?
Y = 4x2 + 6x - 1Use the pq-formula:x = -4/2 +- sqrt ((4/2)2 -(-1))x = -2 +- sqrt((16/4) +1)x = -2 +- sqrt(4 +1)x1 = -2 + sqrt(5)x2 = -2 - sqrt(5)
If the discriminant of a quadratic equation is zero and one root of the equation is 5 what is the value of the other root?
It too will have a value of 5
What value makes c a perfect square 4x2 plus 20x plus c?
c = 25 4x2 + 20x + 25 (2x + 5)(2x + 5)
6x -1 equals 29 what is the value of x² plus x?
6x - 1 = 29 => 6x = 30 => x = 5 Then x2 + x = 25 + 5 = 30
What is 2x-1-6 5 plus 6x?
The value of X in the equation 2x-1-6 5 plus 6x is -3.
