You can put this solution on YOUR website!
(x - 4) (2x^2 + 4) + (x + 4)(x^3 - 1) - (x^2 - x - 1)
\n" ); document.write( "First you have do multiplication using distributive property (a+b)(c+d)=ac+ad+bc+bd
\n" ); document.write( "(x*2x^2+x*4-4*2x^2-4*4) + (x*x^3+x*(-1)+4*x^3+4*(-1))-(x^2-x-1)= remove brackets and remember to change sign if there is - before (...)
\n" ); document.write( "2x^3+4x-8x^2-16+x^4-x+4x^3-4-x^2+x+1= add like items
\n" ); document.write( "x^4+6x^3-9x^2+4x-19\r
