(x+1)(x+2) The degree of the polynomial is

a degree of a polynomial is the greatest power in it

first expand

(x+1)(x+2)

x²+3x+2

the greatest power here is 2

so the degree of this polynomial is 2

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
