Algebra.Com's Answer #242462 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! m^3+5m^2-9m-45=0 is not a quadratic , it is a cubic\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "grouping ___ (m^3 + 5m^2) - (9m + 45) = 0\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "factoring ___ m^2(m + 5) - 9(m + 5) = 0\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "rearranging ___ (m^2 - 9)(m + 5) = 0\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "factoring (again) ___ (m + 3)(m - 3)(m + 5) = 0 \n" ); document.write( " |
