\n" );
document.write( "4x^4-25x^2+36=0  |substition showed x = 2 is a root
\n" );
document.write( "(x-2)(4^3+8x^2-9x-18) |found by dividing 4x^4-25x^2+36 by (x-2)
\n" );
document.write( "(x-2)(4^3+8x^2-9x-18) |substitiution showed x = -2 is a root for 4^3+8x^2-9x-18
\n" );
document.write( "(x-2)(x+2)(4x^2-9)     |found by dividing 4^3+8x^2-9x-18 by (x+2)
\n" );
document.write( "factoring
\n" );
document.write( "(x-2)(x+2)(2x-3)(2x+3)=0
\n" );
document.write( "x = {-2,-2,3/2,-3/2} \n" );
