\n" ); document.write( "Write a quadratic equation with -1/3 and 4 as its roots. Write the equation in standard form.
\n" ); document.write( "
Since \"x+=+-+1%2F3\" is a root, then \"x+%2B+1%2F3+=+0\", or \"3x+%2B+1+=+0\" is a factor
\n" ); document.write( "Since x = 4 is a root, then x - 4 = 0 is a factor
\n" ); document.write( "We can then say that: (3x + 1)(x - 4) = 0
\n" ); document.write( "After FOILing the binomials, we get: \"highlight_green%283x%5E2+-+11x+-+4+=+0%29\" ------ Quadratic equation, in standard form \n" ); document.write( "
\n" );
