You can put this solution on YOUR website!
Once again, denominators cannot be zero, so we have to see what values of c make that so...those values are the \"illegal\" ones...so for
\n" ); document.write( "c^2 + 5c - 14 = 0
\n" ); document.write( "(c+7)(c-2) = 0
\n" ); document.write( "c = -7 or c = 2 and for
\n" ); document.write( "c^2 - 2c - 15 = 0
\n" ); document.write( "(c-5)(c+3) = 0
\n" ); document.write( "c = 5 or c = -3
\n" ); document.write( "Thus c is not allowed to be any of
\n" ); document.write( "-7, 2, 5, or -3 \n" ); document.write( "
