The equation is equivalent to: -3x2 - 12x - 1 = 0
[you could change signs to get 3x2 + 12x + 1 = 0 but that is not required]
The discriminant is (-12)2 - 4*(-3)(-1) = 144 - 12 = 132

What is the discriminant of 2x2 plus 23x plus 63 equals 0?
The discriminant is 25.
How do you find the sum of the roots of the equation x2 plus 5x plus 9 equals 0?
This quadratic equation has no real roots because its discriminant is less than zero.
What is the discriminant in the quadratic equation x2 plus 11x plus 121 equals x plus 96?
The discriminant in the quadratic equation x2 + 11x + 121 = x + 96 is 0.Simplify the equation to the form Ax2 + Bx + C = 0 and you get x2 + 10x + 25 = 0. The discriminant is B2 - 4AC or 100 - (4)(1)(25) or 100 - 100 or 0.Not asked, but answered for completeness - since the discriminant is 0, there is one real solution, namely x = (-10 +/- 00.5) / 2 = -5
What is the discriminant of x2 plus 7x plus 2 equals 0?
The discriminant is b2 - 4ac. In this case, a = 1, b = 7, and c = 2. Just replace and calculate.
What use the discriminant to determine the nature of the roots of x2 plus 2x plus 5 equals 0?
No real roots

The discriminant is 9.
Solve by completing square 2x² - 6x plus 7 equals 0?
This quadratic equation has no solutions because the discriminant is less than zero.
How do you solve 2x squared plus x plus 2 equals 0 by completing the square?
It cannot be solved because the discriminant of the quadratic equation is less than zero
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.
Use the quadratic equation y equals x2 plus 3x plus 9 Calculate the discriminant to determine the number of real roots?
The discriminant is -27 and so there are no real roots.
What is x2 plus 5x plus 9 equals 0?
It has no solutions because the discriminant of the quadratic equation is less than zero.
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.
