List values in order \(\mathrm{A}\), \(\mathrm{B}\), \(\mathrm{C}\). Use commas between values and do not use spaces. Find values for \(\mathrm{A}\), \(\mathrm{B}\), and \(\mathrm{C}\) so that \((5n+\mathrm{A})(\mathrm{B}n+2)\) is equal to \(15n^2+\mathrm{C}n-2\).

Question

Answer

\(\mathrm{A}=-1\), \(\mathrm{B}=3\), \(\mathrm{C}=7\)
