It is given that:
The square below has an area:
4 - 4x + x²
The above expression is a quadratic expression:
The expression can be defined as the combination of constants and variables with mathematical operators.
Using identity: (a - b)² = a² - 2ab + b²
= x² - 4x + 4
= x² -2(2)(x) + 2²
= (x - 2)² or
= (x- 2)(x - 2)
Thus, the side length of each side is (x - 2) meters after using the identity (a - b)² = a² - 2ab + b²
