You can put this solution on YOUR website!
To find the x-intercepts, set y = 0 and solve for x.\r
\n" ); document.write( "\n" ); document.write( " $\"x%5E2+-+4x+%2B+4+=+0\"$ Solve by factoring.
\n" ); document.write( " $\"%28x+-+2%29%28x+-+2%29+=+0\"$ Apply the zero product principle.
\n" ); document.write( " $\"%28x+-+2%29+=+0\"$ You will have a double root.
\n" ); document.write( "If $\"x+-+2+=+0\"$ then, $\"x+=+2\"$ A double root.
