Step-by-step explanation:
1) Use the partial sum method.
1	8	4	9	2
+	8	0	6	2	5
9	0	0	0	0	(10000+80000)
8	0	0	0	(8000+0)
1	0	0	0	(400+600)
1	1	0	(90+20)
7	(2+5)

The characteristic of the repeating shapes in a tessellation is that shapes cannot have spaces between them.
<h3>What is tessellation ?</h3>
When we talk about tessellation, our minds go to a situation in which many shapes especially polygons are packed together without spaces between them.
Thus, the characteristic of the repeating shapes in a tessellation is that shapes cannot have spaces between them.

To complete a square for ax²+bx+c, you first make a=1.
in this case, a is already 1
move c to the right side: x²+14x=-47
next, add (1/2 of b)² to both sides, in this case, b=14, half of 14 is 7, so x²+14x+ 7²=-47+7²
the left side is now a perfect square: (x+7)²=2
x+7=√2 or x+7=-√2
x=√2-7, or x=-2-√7
