You can put this solution on YOUR website!
How many solutions are possible in:
\n" ); document.write( " $\"j%28d%29=+-47d%5E56+=+16d%5E47+-+12d%5E5+%2B+13\"$
\n" ); document.write( "

\r\n" );
document.write( "You have two equal signs there.  Did you mistype that?\r\n" );
document.write( "\r\n" );
document.write( "I'll assume you meant to type a + sign and forgot to press the shift key.\r\n" );
document.write( "\r\n" );
document.write( "So I'll assume it's:\r\n" );
document.write( "

\n" ); document.write( " How many solutions are possible in:
\n" ); document.write( " $\"j%28d%29=+-47d%5E56+%2B+16d%5E47+-+12d%5E5+%2B+13\"$
\n" ); document.write( "

\r\n" );
document.write( "Also, your teacher or book author misstated the sentence.\r\n" );
document.write( "\r\n" );
document.write( "Only equations and inequalities can be said to have solutions.\r\n" );
document.write( "\r\n" );
document.write( "Functions cannot be said to have solutions.  They have zeros.\r\n" );
document.write( "\r\n" );
document.write( "So I'll assume the question was:\r\n" );
document.write( "

\n" ); document.write( " How many zeros (or roots) are possible in:
\n" ); document.write( " $\"j%28d%29=+-47d%5E56+%2B+16d%5E47+-+12d%5E5+%2B+13\"$
\n" ); document.write( "

\r\n" );
document.write( "The rule is:\r\n" );
document.write( "\r\n" );
document.write( "It is possible for an n-degree polynomial to have as many as \r\n" );
document.write( "n zeros or roots.\r\n" );
document.write( "\r\n" );
document.write( "Therefore since the polynomial function:\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "has degree 56, the largest exponent of a variable, then it is \r\n" );
document.write( "possible for it to have as many as 56 zeros or roots.\r\n" );
document.write( "\r\n" );
document.write( "If you must use the word \"solution\", you can say: \r\n" );
document.write( "\r\n" );
document.write( "It is possible for the polynomial equation\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "to have as many as 56 solutions.\r\n" );
document.write( "\r\n" );
document.write( "So the correct choice would be (b).\r\n" );
