The American boy went over to the pond to see what was over there. We need to capitalize the beginning of every sentence, as well as capitalize every ethnic background. Additionally, the sentence used the wrong type of "there," and a period had to be added to the end.

### Subject:Algebra

Question:

What is the solution to the equation: ((x+2)/2)=(4/x)

You can cross multiple these and set them equal to each other. So, 2(4)=x(x+2). 8=(x^2)+2x... Then we have to set equal to zero, so that we can factor to find the solutions. X^2+2x-8=0 (x+4)(x-2)=0 works for this equation when using the FOIL method. x+4=0, x-2=0 x=-4, x=2
