x^2+(1/2)=3/4

x^2+(1/2)+(1/4)^2=3/4+(1/4)^2

(x+1/4)^2=13/16

x+1/4=+-sqrt 13/16

x+1/4=+-sqrt 13/4

x=-1/4+-sqrt 13/4

x=-1+-sqrt 13/4

**Reiny**, Sunday, November 18, 2007 at 11:45amx^2+(1/2)=3/4 should say

x^2+(1/2**x**)=3/4 also in the line that follows that you left out the x in the second term

to avoid problems with order of operation, write your final answer this way

x=(-1+-sqrt 13)/4 the way you have it only the square root term would be divided by 4
