x^2+10x+10=0
\r
\n" ); document.write( "\n" ); document.write( "well first you need to get the x's by them selves so subtract 10 from both sides
\r
\n" ); document.write( "\n" ); document.write( "x^2+10x=-10
\r
\n" ); document.write( "\n" ); document.write( "now take 1/2 of 10 then square it and then add it to both sides
\r
\n" ); document.write( "\n" ); document.write( "x^2+10x+(1/2(10))^2=-10+(1/2(10))^2
\n" ); document.write( "x^2+10x+(5)^2 = -10 + (5)^2
\n" ); document.write( "x^2+10x+25 = -10 + 25
\r
\n" ); document.write( "\n" ); document.write( "now take the square root of x^2 and 25 and combine like terms on the right side
\r
\n" ); document.write( "\n" ); document.write( "(x+5)^2=15
\r
\n" ); document.write( "\n" ); document.write( "now take the square root of both sides
\r
\n" ); document.write( "\n" ); document.write( "x+5 = \"sqrt+%2815%29\"
\n" ); document.write( "x = \"sqrt+%2815%29\" - 5
\n" ); document.write( "
\n" );
