Is this a quadratic equation? there's only one 'x'. How do i solve this problem? 2(x-3)^2-50=0.
\n" ); document.write( "------------------
\n" ); document.write( "It's a quadratic, the x term (x-3) is squared.
\n" ); document.write( "If you expand it you get and x^2 term.
\n" ); document.write( "------
\n" ); document.write( "The easiest way to solve it is
\n" ); document.write( "2(x-3)^2-50=0
\n" ); document.write( "2(x-3)^2 = 50
\n" ); document.write( "(x-3)^2 = 25
\n" ); document.write( "x-3 = 5 --> x = 8
\n" ); document.write( "------
\n" ); document.write( "x-3 = -5 --> x = -2
\n" ); document.write( " \n" ); document.write( "

\n" );
