Find a polynomial function of degree 3 with -1,3,4 as zeros.
\n" ); document.write( "if zeros are at: -1,3,4
\n" ); document.write( "we conclude that the \"factors\" of the polynomial must be:
\n" ); document.write( "(x+1)
\n" ); document.write( "(x-3)
\n" ); document.write( "(x-4)
\n" ); document.write( ".
\n" ); document.write( "multiplying all three factors above we get our polynomial:
\n" ); document.write( "(x+1)(x-3)(x-4)
\n" ); document.write( "(x^2-2x-3)(x-4)
\n" ); document.write( "x(x^2-2x-3)-4(x^2-2x-3)
\n" ); document.write( "(x^3-2x^2-3x)-(4x^2-8x-12)
\n" ); document.write( "x^3-2x^2-3x-4x^2+8x+12
\n" ); document.write( "x^3-6x^2-3x+8x+12
\n" ); document.write( "x^3-6x^2+5x+12 (this is what they're looking for)\r
