1) 2x^2-5x-10=0 using the quadratic equation we get:
\n" ); document.write( " $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( "x=(5+-sqrt[-5^2-4*2*-10])/2*2
\n" ); document.write( "x=(5+-sqrt[25+80])/4
\n" ); document.write( "x=(5+-sqrt105)/4
\n" ); document.write( "x=(5+-10.25)/4
\n" ); document.write( "x=(5+10.25)/4
\n" ); document.write( "x=15.25/4
\n" ); document.write( "x=3.81 answer.
\n" ); document.write( "x=(5-10.25)/4
\n" ); document.write( "x=-5.25/4
\n" ); document.write( "x=-1.31 answer.
