1) S = -10(2)^2+21(2)+7.
\n" ); document.write( "2) S = -10(4)^2+21(4)+7.
\n" ); document.write( "i think u have these parenthesies out of order if x=2 and x=4 for 2nd problem they should look like this:
\n" ); document.write( " $\"S=-10%282%5E2%29%2B21%282%29%2B7\"$ now simple order of opperations:() then * then +
\n" ); document.write( " $\"S=-10%284%29%2B21%282%29%2B7\"$
\n" ); document.write( " $\"S=-40%2B42%2B7\"$
\n" ); document.write( " $\"S=9\"$
