PROBLEM:
\n" ); document.write( "If a+b+c = 8 and ab + bc + ac = 13 , find the value of (a^2) + (b^2) + (c^2)\r
\n" ); document.write( "\n" ); document.write( "SOLUTION:
\n" ); document.write( "(a+b+c)^2=a^2+2ab+2ac+b^2+2bc+c^2
\n" ); document.write( "(8)^2=a^2+b^2+c^2 2(13)
\n" ); document.write( "64 - 26 = a^2+b^2+c^2
\n" ); document.write( "a^2+b^2+c^2 = 38
\n" ); document.write( " \n" ); document.write( "

\n" );
