Question

Is this a polygon? [(3x+12)•(4x+4)]-(3x+8)-(4x)=

Answer 1

Not a polygon

Explanation:

[(3x+12)•(4x+4)]-(3x+8)-(4x)

[12x² + 12x + 48x + 48] - 3x - 8 - 4x

12x² + 60x + 48 - 7x - 8

12x² + 53x + 40

This is a degree 2 (quadratic) polynomial, not a polygon.

A polygon is an n-sided figure.

Example: A rectangle --> A four-sided polygon
