Hello,
\n" ); document.write( "Let's have x represent the number. Therefore the equation will be:
\n" ); document.write( "x^2=8x+20 Subtract 8x and 20 from both sides to get:
\n" ); document.write( "x^2-8x-20=0 This can be factored into:
\n" ); document.write( "(x-10)(x+2)=0 Solve for x:
\n" ); document.write( "x=10
\n" ); document.write( "x=-2
