    i dont think thats right lol but the very first one you attached is right. now i just need to figure out how to get -3/4 as the second answer. The correct answer is 3 and -3/4 i just dont know how to show the work for the second answer.

    I too, am having trouble following the work on the second attachment. Although 3 is a correct solution.

    Well the quadratic may have two roots, the 3 and another. I am hung up on the second line of the attachment, where he put the numerator over the LCD and got x(2x+2) I keep getting x(2x-1) for the first fraction. I will look into it further and post here later. Right now I got to put my dogs up.

    But first lets see if -3/4 is an answer -3/4 2 1 ------ - --------- = ---- -3/4 +2 2(-3/4)-1 5 -3/4 2 1 ------ - ---------- = ---- 5/4 -5/2 5 -3/5 - (-4/5 = 1/5 It checks as an answer

    The solution to that quadratic does not come out to 3 or -3/4. the results of\[x=1/16(3\pm 3\sqrt{65}\] is an irrational number not the integer 3, or the fraction -3/4 something is wrong (maybe with me lol)
