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, then
- If it is 3x2 ± 6x - 5, then

What is -8x - 70 equals 6x?
It is an equation and the value of x is -5
What is x times 6?
You simply write that as -6x. You can't calculate the actual value, unless you happen to know the value of "x".
6x - 5 -5?
6x - 5 -5 = 0 6x -10 = 0 +10=+10 6x=10 x= about 1.4
What is 6x -5 31 equals?
If you mean: 6x-5 = 31 then x = 6
What value for x makes the following equation TRUE 6x-5 equals 31?
6!
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
-3x squared equals 5 plus 3x?
-3x2 = 5 + 3x (add 3x2 to both sides)0 = 3x2 + 5 + 3x or3x2 + 3x + 5 = 0 (since the discriminant is less than zero, we have complex roots)x = [-3 ± √[(32 - 4(3)(5)]]/2(3)x = [-3 ± √(9 - 60)]/6x = (-3 ± √-51)/6x = (-3 ± i√51)/6x = (-3 + i√51)/6 = -1/2 + (√51/6)i orx = (-3 - i√51)/6 = -1/2 - (√51/6)i
What is the answer to this equation 3x2 plus 6x plus 24 equals 0?
From what i understand the equation is like this; (3 * 2 ) + 6x + 24 = 0 6 + 6x +24 = 0 6x = - 24 - 6 6x = - 30 x = - 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.
What is the x-coordinate of the of the vertex of y equals -3x2 plus 12x-5?
You can find the x-coordinate of it's vertex by taking it's derivative and solving for zero: y = -3x2 + 12x - 5 y' = -6x + 12 0 = -6x + 12 6x = 12 x = 2 Now that we have it's x coordinate, we can plug it back into the original equation to find it's y coordinate: y = -3x2 + 12x - 5 y = -3(2)2 + 12(2) + 5 y = -12 + 24 + 5 y = 17 So the vertex of the parabola y = -3x2 + 12x - 5 occurs at the point (2, 17).
Factor the polynomial 3x2-9x-30?
3x2-9x-30 =3x2+6x-15x-30 =3x(x+2)-15(x+2) =(3x-15)(x+2) OR 3(x - 5)(x+2)
What is the derivative of 3X squared plus 5x plus 2?
f(x) = 3x2 + 5x + 2fprime(x) = 6x + 5
What is the discriminant value in 4x2 6x 5?
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 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'.
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 is x times 6?
You simply write that as -6x. You can't calculate the actual value, unless you happen to know the value of "x".
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
