The area of the square in terms of x is

16x² – 8x + 1Step-by-step explanation:The formula of the area of a square is A = L², where L is the

length of its side

∵ The length of a side of a square is 4x – 1

∴ L = (4x – 1)

∵ The area of the square is A = L²

∴ A = (4x – 1)²

To solve bracket power 2

The first term is 4x and the second term is -1

∵ (4x)² = 16x²

∵ (4x)(-1)(2) = -8x

∵ (-1)² = 1

∴ (4x -1)² = 16x² + -8x + 1

∴ (4x -1)² = 16x² – 8x + 1

∴ A = 16x² – 8x + 1
