The area of the square in terms of x is 16x² - 8x + 1
Step-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
The area of the square in terms of x is 16x² - 8x + 1
