Answer:

2x\³ + 3x\² = x(x\²) + (x- 2)\² is not quadratic

Explanation:

Given

2x\³ + 3x\² = x(x\²) + (x- 2)\²

Required

Determine if it is quadratic

We have:

2x\³ + 3x\² = x(x\²) + (x- 2)\²

Open brackets

2x\³ + 3x\² = x^3 + x^2 - 4x + 4

Collect like terms

2x\³ - x^3 + 3x\² -x^2 + 4x - 4=0

x^3 + 2x\²+ 4x - 4=0

A quadratic equation is represented as:

ax^2 +bx + c =0

Hence:

x^3 + 2x\²+ 4x - 4=0 is not quadratic

Mashcka [7]

A study of how people tend to act when presented with a moral problem or dilemma is known as descriptive ethics.

Descriptive ethics is the field of ethics carried out to understand people's behavior and moral values.

It is easy to perform and it is usually done by asking different questions to a group of people. Descriptive ethics is also called comparative ethics. Results from descriptive ethics can be used under the physiological status of the group.

It is also experimental research carried out to undermine the ethical patterns of society. Other forms of ethical study like the expressive study are done to understand the actions or words of the individual.
