You can put this solution on YOUR website!
%2816x%5E2+%2B+8x+-+4%29+%2F+4
Each term get divided by 4
This is no more difficult than:
+%2816+%2B+8+-+4%29%2F4
If I do the addition,
20%2F4+=+5
Now, dividing each term by 4,
16%2F4+%2B+8%2F4+-+4%2F4+=+4+%2B+2+-+1
4+%2B+2+-+1+=+5
---------------------
The solution to your problem is
%2816x%5E2+%2B+8x+-+4%29+%2F+4+=+16x%5E2%2F4+%2B+8x%2F4+-+4%2F4
16x%5E2%2F4+%2B+8x%2F4+-+4%2F4+=+4x%5E2+%2B+2x+-+1 answer
