Let x be the integer. We get
\n" ); document.write( " $\"x+%2B+x%5E2+=+30\"$
\n" ); document.write( "rewriting, we get
\n" ); document.write( " $\"x%5E2+%2B+x+=+30\"$
\n" ); document.write( "setting equal to 0, we get
\n" ); document.write( " $\"x%5E2%2Bx-30=0\"$
\n" ); document.write( "factoring, we get
\n" ); document.write( " $\"%28x-5%29%28x%2B6%29=0\"$
\n" ); document.write( "solving each parenthesis, we get
\n" ); document.write( "x = 5 and x = -6; choice (d) \n" ); document.write( "
