Is 4 - 3x plus 5x2 a polynomial?
Yes. If you add, subtract or multiply (but not if you divide) any two polynomials, you will get a polynomial.
What is 2x to the third power plus 8x to the second power plus 3x plus 12 when factoring each polynomial by grouping?
The polynomial below is a perfect square trinomial of the form A2 -2ab plus b2 9x2-36x plus 16 True or False?
A polynomial expression is one with a degree higher than 0. Hence, all constants will meet your criterion. Note that (x+2) or [sin(2x)+4] is a polynomial of degree 1. The following is a trivial (normally ignored; inconsequential) non-polynomial: (5x2 - 2x2 - 3x2 + 2) ======================================
