Final answer:
The expression '3x minus x squared' is represented as 3x - x², which is a simplified quadratic polynomial. It does not involve the rules of exponents directly, nor does it represent a complete quadratic equation suitable for the quadratic formula without a constant term.
Step-by-step explanation:
The expression 3x minus x squared can be written algebraically as 3x - x². This is a polynomial in quadratic form, where you have a linear term (3x) and a quadratic term (-x²). To simplify or solve this equation, you would typically rearrange or factor it, depending on the context in which it is used. However, as it stands, it is already in a simplified form.
In relation to the rules of exponents given such as x¹x¹ = x(p+q), this equation does not directly apply as we are not dealing with a multiplication of the same base with different exponents.
