Which of the following is a valid step in the solution of 4sqrt2x+4sqrt(x)+3=0

          4-√x-3  =  0

          original equation            4-√x-3  =  0          isolate          -√x  =  -4+3+0          tidy up            √x  =  1

          raise both sides to the second power          (√x)2  =  (1)2          after squaring            x  =  1

          rearranged equation          x  -1  =  0          add    1    to both sides          x  =  1          a possible solution is :           x  =  1

          original equation, root isolated, after tidy up          √x  =  1          plug in 1 for    x              √(1)  =  1            simplify            √1  =  1            solution checks           solution is:               x  = 1

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
