Question

Can someone answer plz

Answer 1

1.D 2. A 3.C 4.D

1 Is the monomial as it only contains one expression.

2. Is the difference of squares because something squared minus something squared.

3. Is standard because it is of the form

`a_nx^n+ a_(n-1)x^(n-1)+...+a_1x+a_0`

4. We know D is the not the monomial simply because its power is negative which means it does not fit the definition of a polynomial.
