If (p(x)=(a-1)x^2+(a+3)x+2) has degree (0), what happens?

Answer and explanation

Correct answer: No such a exists

For a polynomial to have degree 0, it must reduce to a non-zero constant. Since the constant term here is 2, the coefficients of both x-terms must be zero: a-1=0 and a+3=0. These give a=1 and a=-3 respectively, which cannot hold for the same value of a. Therefore, no such a exists. Exam tip: for degree 0, set the coefficients of every variable term equal to zero.
