Can a polygon be a pentagon yes or no answer!


Yes, a pentagon can be a polygon.

Any shape with straight sides can be a polygon, including hexagons, pentagons, triangles, squares, rectangles, etc. But this does not include shapes such as a circle or oval since they do not have straight sides.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
