What is the answer to x2 9?

Example
ProblemSolve using the Square Root Property. x2 = 9
x2 = 9 x = x = ±3Since one side is simply x2, you can take the square root of both sides to get x on one side. Don't forget to use both positive and negative square roots!
Answerx = ±3 (that is, x = 3 or −3)

What makes 2 equations have no solution?

The coefficients are the numbers alongside the variables. The constants are the numbers alone with no variables. If the coefficients are the same on both sides then the sides will not equal, therefore no solutions will occur.

Are there 2 answers for the quadratic formula?

There are commonly two solutions to quadratic equations because the solutions are where the parabola crosses the -axis. If the vertex is below the -axis and the parabola opens up, the graph will cross twice, and if the vertex is above the -axis and the parabola opens down, the graph will, again, cross twice.

What is the answer to x2?

x2 can be calculated by multiplying the value of x with itself. Example 1: Let's say x represents the number 7. x 2 = 7 × 7 = 49 . Example 2: x squared plus x squared equals 2 times x squared.
