Hello,
\n" ); document.write( "First off to make this a bit more easier to confront, take out 4x^2 like this:
\n" ); document.write( "36x^4-8x^3-28x^2 Rewritten as:
\n" ); document.write( "4x^2(9x^2-2x-7) Now we can factor this to get:
\n" ); document.write( "4x^2(9x+7)(x-1) Solve for x we get:
\n" ); document.write( "x=0
\n" ); document.write( "x=1
\n" ); document.write( "x=-7/9
\n" ); document.write( "Plug these numbers in to see if they work.
