You can put this solution on YOUR website!
The x intercept is where the value of y is 0 so you are trying to solve
\n" ); document.write( "\"0+=+x%5E3-2x%5E2-8x\"
\n" ); document.write( "Factorise by taking out a common factor of x
\n" ); document.write( "\"0+=+x%28x%5E2-2x-8%29\"
\n" ); document.write( "Factorise the trinomial by finding two numbers with a sum of -2 and a product of -8
\n" ); document.write( "\"0+=+x%28x-4%29%28x%2B2%29\"
\n" ); document.write( "To get an answer of 0 one of the numbers multiplied together must be 0.
\n" ); document.write( "So either x = 0 or x-4=0 or x+2=0
\n" ); document.write( "So the y intercepts are 0,4 and -2
\n" ); document.write( "
\n" );
