How many are you expecting ? How will you know if we give you all of them,
or only some of them ?
Since the highest power of the variable in the equation is '2', ("x2"),
the equation has exactly two solutions.
25x2 - 100 = 0
Divide each side by 25:
x2 - 4 = 0
Add 4 to each side:
x2 = 4
Take the square root of each side:
x = +4 and -4
And there are your two solutions.

Do all quadratic equation have a solution?
No. Some have two solutions where as some have none.
What is bratu equation?
the Bratu's equation is a differential equation which is non-linear (such as, if we have some solutions for it, a linear combinaison of these solutions will not be everytime a solution). It's given by the equation y''+a*e^y=0 or d²y/dy² =-ae^y.

How many solutions does x equals 8have?
A solution to an linear equation cx + d = f is in the form x = a for some a, we call a the solution (a might not be unique). Rewrite your sentence: x = 8, 8 is unique. So how many solution does it have?
How do you find the roots of and equation?
The roots of an equation means the solutions of an equation. Different methods have been developed for different kinds of equation. It is not possible to give an overview in one or two paragraphs, but in simpler cases, the same operation is done on both sides of the equation, with the aim of "isolating" the variable you are solving for, that is, having it alone on one side. In some complicated cases, no "explicit" solutions exist, and "numerical" solutions have to be used; this basically means using trial-and-error.
Which ordered pair is a solution of the equation 2x - 3y equals 18?
There are an infinite number of solutions to this equation, some of which are (9,0), (12,2), (15,4), (18,6), (21,8)
Lsquare plus msquare plus nsquare equals 1?
This equation describes all the points on the unit sphere. There is an infinite number of solutions. Some quick integer solutions would be (1,0,0) and (0,1,0) and (0,0,1) which are the one the axes.
Do all quadratic equation have a solution?
No. Some have two solutions where as some have none.
Can you solve for a variable in a equation?
Yes, that is often possible. It depends on the equation, of course - some equations have no solutions.

When solving a radical equation you should first isolate the radical and then?
It often helps to square both sides of the equation (or raise to some other power, such as to the power 3, if it's a cubic root).Please note that doing this may introduce additional solutions, which are not part of the original equation. When you square an equation (or raise it to some other power), you need to check whether any solutions you eventually get are also solutions of the original equation.

What is k in equation V equals tk?
It is impossible to answer the question without some information about V or t or what the equation is meant to represent.
What is a solution for these ordered pairs x plus y equals 12 and y equals 12 - x?
x + y = 12 y = 12 - x These equations are the same, so we only need to consider one of them: x + y = 12 Any (x,y) ordered pairs that satisfy this equation are solutions. Because this equation denotes a line, there are infinitely many solutions, but here are some examples: (0, 12) (1, 11) (2, 10) (3.5, 8.5) (12, 0)
How do you know when an Equation has an infinity solutions without solving the equation?
You can't really know that in all cases. But with some practice in working with equations, you'll start to notice certain patterns. For example, you'll know that certain functions are periodic, and that an equation such as: sin(x) = 0 have infinitely many solutions, due to the periodicity of the function. This one is easy; we can make some small changes: sin(2x + 3) = 0.5 Here it isn't as easy to guess the exact solutions of the equation, but due to our knowledge of the periodicity of the sine function, we can assume that it has infinitely many solutions. Another example: a single equation with two or more variables normally has infinitely many solutions, for example: y = 3x + 2
