Still some ambiguity however.</p>\n <p><strong>12/08/2012:</strong></p>\n <p>Back to one input of a fraction and trapped input in Forbidden Strings.</p>\n <p>Used the except feature of ranges to get non-degenerate examples.</p>\n <p>Checked calculation.OK.</p>\n <p>Improved display in content areas.</p>\n <p><strong>02/02/2013:</strong></p>\n <p>Added instructions to simplify the numerator.</p>",
"description": "<p>Express $\\displaystyle \\frac{a}{(x+r)(px + b)} + \\frac{c}{(x+r)(qx + d)}$ as an algebraic single fraction over a common denominator. The question asks for a solution which has denominator $(x+r)(px+b)(qx+d)$.</p>",
