You can put this solution on YOUR website!
It follows that 2 must be a double root. A useful property of polynomials is that if r is a root, then x-r is a factor of the polynomial. We can express the polynomial in the form $\"C%28x-2%29%5E2+=+C%28x%5E2+-+4x+%2B+4%29+=+Cx%5E2+-+4Cx+%2B+4C\"$ where C is a nonzero constant. \n" ); document.write( "
