can someone tell me if i did the problem correct (solve by completing the square) 4x^2+2x-3=0
x^2+(1/2)=3/4 should say
x^2+(1/2x)=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
