Given: The side of a square is (3x - 6) units.
Note that (a + b)² = a² + 2ab + b².
Part A
The area of the square is
A = (3x - 6)(3x - 6)
= (3x)² + 2(3x)(-6) + (-6)²
= 9x² - 36x + 36
Part B
The area is a 2nd-degree polynomial, or a quadratic function, or parabola.
Part C
A 2nd-degree polynomial is of the form
f(x) = ax² + bx¹ + cx⁰ = ax² + bx + c
where a,b,c are constants (coefficients of the polynomial).
The area obtained in Part A has the coefficients
a = 9, b = -36, c = 36.
The polynomial is closed because it is completely defined by multiply and addition operations.
