If they are quadratic equations then if their discriminant is less than zero then they have no solutions
In the graph of a quadratic equation, the plotted points form a parabola. This parabola usually intersects the X axis at two different points. Those two points are also the two solutions for the quadratic equation. Alternatively: Quadratic equations are formed by multiplying two linear equations together. Each of the linear equations has one solution - multiplying two together means that the solution for either is also a solution for the quadratic equation - hence you get two possible solutions for the quadratic unless both linear equations have exactly the same solution. Example: Two linear equations : x - a = 0 x - b = 0 Multiplied together: (x - a) ( x - b ) = 0 Either a or b is a solution to this quadratic equation. Hence most often you have two solutions but never more than two and always at least one solution.
The term "discriminant" is usually used for quadratic equations. If the discriminant is zero, then the equation has exactly one solution.
If you have a quadratic equation and there is no x to put into the equation to get zero. The graph is like a U that is above the x axis or a cap that is below the x axis.
If the discriminant of the quadratic equation is greater than zero then it will have two different solutions. If the discriminant is equal to zero then it will have two equal solutions. If the discriminant is less than zero then it will have no real solutions.
They are the solutions for the reduced quadratic.

Linear equations are polynomial equations of the first degree, meaning they have the highest exponent of one, and they graph as straight lines. In contrast, quadratic equations are polynomial equations of the second degree, characterized by the highest exponent of two, and they graph as parabolas. This fundamental difference in degree affects their solutions and the nature of their graphs. Additionally, linear equations have a single solution, while quadratic equations can have zero, one, or two solutions.
Wolfram Alpha can solve not just quadratic equations, but all sorts of equations. Note that in this particular website, you can see the solution for free, but you need a paid subscription to show the steps. I am sure there are other websites that can help you as well; you may want to try a Web search for "quadratic equation", for example. On the other hand, you should definitely learn to solve quadratic equations on your own.
A quadratic equation ax2 + bx + c = 0 has the solutions x = [-b +/- sqrt(b2 - 4*a*c)]/(2*a)
The term "discriminant" is usually used for quadratic equations. If the discriminant is zero, then the equation has exactly one solution.
ax3 + bx2 + cx x(ax2 + bx + c) you get one answer as 0.
A quadratic solution refers to the solution of a quadratic equation, which is typically in the form (ax^2 + bx + c = 0), where (a), (b), and (c) are constants and (a \neq 0). The solutions can be found using the quadratic formula: (x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}). These solutions can be real or complex, depending on the discriminant ((b^2 - 4ac)). Quadratic equations are fundamental in algebra and have various applications in mathematics and science.
A quadratic equation can have two real solutions, one real solution, or two complex solutions, none of them real.
so you can find the solution for the x-values. the x-intercepts are when the graph crosses the x-axis
Yes it is possible. The solutions for a quadratic equation are the points where the function's graph touch the x-axis. There could be 2 places to that even if the graph looks different.
