How many solutions are there to this equation?

If solving an equation yields a statement that is true for a single value for the variable, like x = 3, then the equation has one solution. If solving an equation yields a statement that is always true, like 3 = 3, then the equation has infinitely many solutions.

How many real solutions does x 2 =- 1 have?

two complex
If you write it as x2 = –1 and try to take the square root of each side, you run into trouble. Not until you have the imaginary numbers can you write that the solution of this equation is x = +/–i. The equation has two complex solutions.

How many solutions does x 2 2x 1 have?

4.2 Solving x2+2x+1 = 0 by Completing The Square . This quadratic equation has one solution only.

How many solutions does the equation x?

Sample Problems The equation x = x has infinitely many solutions: any value of x will work, since x is always equal to itself. The equation y2 = -5 has no real number solutions because the square of any real number is positive.

How many solutions does this system have?

A system of two equations can be classified as follows: If the slopes are the same but the y-intercepts are different, the system has no solution. If the slopes are different, the system has one solution. If the slopes are the same and the y-intercepts are the same, the system has infinitely many solutions.

How many solutions does x 2 have?

In general, all equations of the form x2 = a, where a is a positive number, will always give two solutions, namely x = – / a or x = / a. We use the symbo 소 to mean “plus or minus”.

Does x 2 have a solution?

X^2=n in the set of real numbers it has infinitely many solutions for assuming n positive or zero x=sqrt(n) and for a positive or zero n the function x=sqrt(n) is unbounded. So the range is [0,infinity[ which means infinite number of solutions.

Can you factor x 2 2x 1?

It cannot be factored. You would have to use the quadratic formula to solve for x.
