THESE PROBLEMS DON'T NEED A CALCULATOR IF YOU KNOW HOW TO SOLVE SQUARE ROOTS, MULTIPLY & DIVIDE (LONG METHOD).

\n" ); document.write( "3x^2-2x+7=0
\n" ); document.write( "using the quadratic equation $\"x=%28-b%2B-sqrt%28b%5E2-4%2Aa%2Ac%29%29%2F%282%2Aa%29\"$ we get:
\n" ); document.write( "x=(2+-sqrt[-2^2+4*3*7])/2*3
\n" ); document.write( "x=(2+-sqrt[4-84])/6
\n" ); document.write( "x=(2+-sqrt-80)/6
\n" ); document.write( "x=(2+-8.944i)/6
\n" ); document.write( "x=2/6-8.944i/6
\n" ); document.write( "x=1/3+1.49i answer.
\n" ); document.write( "x=1/3-1.49i answer.
\n" ); document.write( "then:
\n" ); document.write( "(x-1/3)^2=(1/3+1.49i-1/3)^2=(1.49i)^2=-2.22 answer.
\n" ); document.write( "or (x-1/3)^2=(1/3-1.49i-1/3)^2=(-1.49i)^2=-2.22 answer. \n" ); document.write( "

\n" );
