You can put this solution on YOUR website!
+x%5E2+-+8x+%2B+7+=+0+
You can complete the square
+X%5E2+-+8x+%2B+%28+8%2F2+%29%5E2+=+-7+%2B+%28+8%2F2+%29%5E2+
+x%5E2+-+8x+%2B+16+=+-7+%2B+16+
+%28+x+-+4+%29%5E2+=+3%5E2+
Take the square root of both sides
+x+-+4+=+3+
+x+=+7+
and, taking the negative square root,
+x+-+4+=+-3+
+x+=+1+
