Question

How many solutions are there to square root x =9

Answer 1

There are 2 solutions to square root x = 9

They are 3, and -3

Explanation:

The square root of x=9 has 2 solutions,

The square root means, for a given number, (in our case 9) what number times itself equals the given number,

Or, squaring (i.e multiplying with itself) what number would give the given number,

so, we have to find the solutions to
`√(9)`

since we know that,

`(3)(3) = 9\\and,\\(-3)(-3) = 9`

hence if we square either 3 or -3, we get 9

Hence the solutions are 3, and -3
