1. Square both side.
2x+5 equals x square
Move everything to one side.
X square-2x-5=0
Since this time, we can't factor very well. We need to use the quadratic formula.
-b+- square root b square- 4ac divided by 2a
This gives: -(-2)* square root( 4-4(1)(5))/ 2
Notice that we get 2 plus and minus square root of -16.
Which is an imagery/ complex solution.
The value of x could be 2+i4/2 or 2-i4/2
