Radical 2x+5 equals x 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
