Question

Find the area of a square one side measures (x-2)

Answer 1

Area of a square is side*side.

side = (x - 2)

Area = side*side = (x - 2)*(x - 2)

x(x - 2) -2(x - 2)

x*x - 2*x - 2*x -2*(-2)

x² - 2x - 2x + 4

x² - 4x + 4

Therefore area = x² - 4x + 4 square units.

Hope this helped.

Answer 2

Area of a square:
(x-2)(x-2)
=(x-2)^2
=x^2-2x-2x+4
=x^2-4x+4 unit sq
