The square below has an area of
Solnce55 [7]

Answer:

8-x meters

Step-by-step explanation:

Both 64 and x^2 are perfect squares, since 64=(8)^2 and x^2=(x)^2.

Additionally, 16x is twice the product of the roots of 64 and x^2, since 16x=2(8)(x).

So we can use h the square of a difference pattern to factor:

a^2-2(a)(b)+b^2=(a-b)^2

In this case, a=8 and b=x:

(8)^2-2(8)(x)+(x)^2=(8-x)^2

In conclusion...

64-16x+x^2=(8-x)^2

So the side length of the square is 8-x meters.
