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

How was the idea of citizenship changed throughtout histpry
