Solve this system by Substitution.\r
\n" ); document.write( "\n" ); document.write( "y = x^2 - 8 and 2x + y = 6
\n" ); document.write( " sol:
\n" ); document.write( "y=x^2-8 ---1
\n" ); document.write( "2x+y=6 ---2
\n" ); document.write( "from 2,
\n" ); document.write( "y=6-2x ---3
\n" ); document.write( "put 3 in 1
\n" ); document.write( "ie, x^2-8=6-2x
\n" ); document.write( "x^2+2x-8-6=0
\n" ); document.write( "x^2+2x-14=0
\n" ); document.write( "then solve the resulting quadratic equation.
\n" ); document.write( "GOOD LUCK!
