It is (x+4)(x+5) when factored
a polynomial of degree...............is called a cubic polynomial
15j2(j + 2)
If you mean: x2+3x+2 then it is (x+1)(x+2) when factored
3x2 - 5x - 2 can be factored into (3x + 1) (x - 2)
It is still called a polynomial.
You can't know if a general polynomial is in factored form.
Completely Factored
It can, so the question does not make sense.
It is (x+4)(x+5) when factored
This polynomial is irreducible; it cannot be factored.
5x(3x+4)
a polynomial of degree...............is called a cubic polynomial
The GCF is 3d2, leaving 2d2 3d 4
15j2(j + 2)
It is a quadratic expression and when factored it is: (7x+5)(2x-7)
It is 6x(2x+5) when factored
