+1622 Open up paranthesis by FOILing: 9x^2 + 36x + 12x + 48 = (4x^2 + 8x + 18x^2)/2x
Combine like terms: 9x^2 + 48x + 48 = (22x^2 + 8x)/2x
Factor out top and bottom by 2x, then cancel terms: (22x^2 + 8x)/2x = 2x(11x + 4)/2x = 11x + 4
9x^2 + 48x + 48 = 11x + 4
Combine like terms: 9x^2 + 37x + 44 = 0
Use quadratic formula: \({-37\pm\sqrt{37^2 - (4)(9)(44)}}\over18\) = \({-37 \pm\sqrt{1369 - 1584}}\over18\) = \(-37\pm i\sqrt{215}\over18\) = x
