Question 1047243: show that (5+4√x)squared /2x = 25/2 x^-1 +Px^ -1/2 + Q

i can simplify the brackets into (25+ 40√x+16x)/2x but in the mark scheme they get the same brackets but instead of dividing by 2x they write 1/2 x to the power of -1(25+40rootx+16x) why do they times the brackets by a half x to the power of -1

Because they are equivalent values.
