Dr. Knesis's method would best be described as a <u>"structured observation".</u>


Structured observation is an information gathering strategy in which analysts accumulate information without coordinate contribution with the members (the scientists watch from a far distance) and the gathering method is organized in a very much characterized and procedural way. It enables scientists to gather information that couldn't be gathered utilizing ordinary research techniques like reviews and meetings. Structured observation utilizes a coding technique for information accumulation.

2x³ + 3x² = x(x²) + (x- 2)² check weather the conditions is quadratic equation. plz help me guys. ​
Effectus [21]

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
