They each typically have two solutions, a positive one and a negative one.
If the value under the radical sign (the discriminant) in the quadratic formula is negative, it means that the quadratic equation has no real solutions. Instead, it has two complex (or imaginary) solutions. This occurs because the square root of a negative number is not defined in the set of real numbers, indicating that the parabola represented by the equation does not intersect the x-axis.
The solutions to a quadratic equation on a graph are the two points that cross the x-axis. NB A graphed quadratic equ'n produces a parabolic curve. If the curve crosses the x-axis in two different points it has two solution. If the quadratic curve just touches the x-axis , there is only ONE solution. It the quadratic curve does NOT touch the x-axis , then there are NO solutions. NNB In a quadratic equation, if the 'x^(2)' value is positive, then it produces a 'bowl' shaped curve. Conversely, if the 'x^(2)' value is negative, then it produces a 'umbrella' shaped curve.
If a quadratic function is 0 for any value of the variable, then that value is a solution.
Two cases in which this can typically happen (there are others as well) are: 1. The equation includes a square. Example: x2 = 25; the solutions are 5 and -5. 2. The equation includes an absolute value. Example: |x| = 10; the solutions are 10 and -10.
In a quadratic function, the intersection points with the x-axis represent the values of x where the function equals zero, which are the solutions to the equation. Since a quadratic is typically expressed in the form ( ax^2 + bx + c = 0 ), the y-value at these intersection points is always zero, indicating that the solutions are solely defined by the x-values. Therefore, only the x-values of these intersection points are relevant as they represent the roots of the equation.
An equation with absolute values instead of simple variables has twice as many solutions as an otherwise identical equation with simple variables, because every absolute value has both a negative and a positive counterpart.
Without an equality sign and not knowing the plus or minus value of 11 it can't be considered to be an equation.

They will have 2 different solutions or 2 equal solutions and some times none depending on the value of the discriminant within the quadratic equation
If you mean: ax2+bx+c = 0 which is the general form of a quadratic equation whereas a is > 0 and any increases to the value of a will effect the solutions of the equation.
In the C Programming Language, the fabs function returns the absolute value of a floating-point number
If a quadratic function is 0 for any value of the variable, then that value is a solution.
