You can put this solution on YOUR website!
15-^2x+2 = 13
:
"^" here means raising to a power (exponent); Square root can be written sqrt( )
:
So I assume you mean:
15-sqrt%282x%2B2%29+=+13
:
-sqrt%282x%2B2%29+=+13-15
:
-sqrt%282x%2B2%29+=+-2
Multiply both sides by -1
sqrt%282x%2B2%29+=+2
Square both sides, gets rid of the radical on the left
2x + 2 = 4
2x = 4 - 2
2x = 2
x = 1

Check solution in original equation
15-sqrt%282%281%29+%2B+2%29+=+13
15-sqrt%284%29+=+13
15 - 2 = 13
