space rightwards double arrow space space 1 over straight a left parenthesis straight a squared space plus space 1 right parenthesis space equals space 3
rightwards double arrow space space straight a squared space plus space 1 space equals space 3 straight a
rightwards double arrow space space straight a squared space plus space 1 minus space 3 straight a space equals space 0
rightwards double arrow space space straight a open parentheses straight a space plus space 1 over straight a close parentheses minus 3 straight a space equals space 0
rightwards double arrow space space straight a open parentheses straight a space plus space 1 over straight a minus space 3 close parentheses space equals space 0
rightwards double arrow space space space straight a space plus space 1 over straight a space minus space 3 space equals space 0
rightwards double arrow space space space space straight a space plus space 1 over straight a space equals space 3
If straight x space plus space 1 over straight x space equals space straight a space comma then straight x cubed space plus space 1 over straight x cubed space equals space straight a cubed space minus space 3 straight a 
therefore space straight a cubed space plus space 1 over straight a cubed space equals space 27 space minus space 9 space equals space 18
therefore space space fraction numerator straight a to the power of 6 plus 1 over denominator straight a cubed end fraction space equals space straight a cubed space plus space 1 over straight a cubed space equals space 18
