Sagot :
Answer:
add 6 unit tiles
Step-by-step explanation:
The square is completed when the algebra tile grid pattern is a square. This one will be a square when 6 more unit tiles are added to fill the empty spaces at the bottom right.
We need to add 6 to complete squares.
What must be added to complete the square?
Here we have the expression:
x^2 + 8x + 10
By looking at the image, we can see that we need to add 6 cubes of the ones with the digit 1.
That is equivalent to adding 6 to our expression (and we also subtract 6 so we don't change it) then we have:
x^2 + 8x + 10 + 6 - 6
(x^2 + 8x + 10 + 6) - 6
(x^2 + 8x + 16) - 6
(x^2 + 2*4*x + 4^2) - 6
(x + 4)^2 - 6
So we completed squares, then we conclude that we need to add 6 to complete squares.
