The expression x² + 8x + 16 represents the area of the square.
What is the area of the square?
The area of the square is defined as the product of the length and width.
Given data as:
A square has a side length of (x+4)
The area of the square = (x+4)(x+4)
The area of the square = (x+4)²
The area of the square = x² + 2(x)(4) + 4²
The area of the square = x² + 8x + 16
Hence, the expression x² + 8x + 16 represents the area of the square.
