What else can I help you with?
Which of the following systems of equations has no solution?
If they are quadratic equations then if their discriminant is less than zero then they have no solutions
Why are there usually two solutions to a quadratic equation?
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.
If the discriminant of an equation is zero then?
The term "discriminant" is usually used for quadratic equations. If the discriminant is zero, then the equation has exactly one solution.
What is a no solution factoring or equations?
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.
Why are there usually two solutions in quadratic equations and when do they only have one solution?
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.
What is the solution of rational equations reducible to quadratic?
They are the solutions for the reduced quadratic.
Which of the following systems of equations has no solution?
If they are quadratic equations then if their discriminant is less than zero then they have no solutions

What is the difference of linear equations from quadratic equations?
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.
What is a great website to use for quadratic equations?
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.
What is the solution of rational equations reducible to quadratic equation?
A quadratic equation ax2 + bx + c = 0 has the solutions x = [-b +/- sqrt(b2 - 4*a*c)]/(2*a)
If the discriminant of an equation is zero then?
The term "discriminant" is usually used for quadratic equations. If the discriminant is zero, then the equation has exactly one solution.
What type of solution do you get for quadratic equations where d 0?
ax3 + bx2 + cx x(ax2 + bx + c) you get one answer as 0.
Why do you need x intercepts for quadratic equations?
so you can find the solution for the x-values. the x-intercepts are when the graph crosses the x-axis
Most quadric equations have?
A quadratic equation can have two real solutions, one real solution, or two complex solutions, none of them real.
Is it possible to have different quadratic equations with the same solution Why?
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.
How many solutions can a quadratic-linear system have?
A quadratic-linear system can have either zero, one, or two solutions, depending on the specific equations involved. If the quadratic and linear equations intersect at two points, there are two solutions; if they touch at one point (the vertex of the quadratic lies on the line), there is one solution; and if they do not intersect at all, there are zero solutions. The nature of the solutions is determined by the relative positions of the parabola and the line in the coordinate plane.
