# Use factor theorem to determine whether x+3 is factor of x^{2} + 2x – 3 or not.

Answer :

The coefficient form of the polynomial:

⟹ 1.x^{2} + 2.x – 3

(1, 2, -3)

Since the last term is zero which indicates that the polynomial on dividing by x + 3 leaves no remainder and hence x + 3 is the factor of x^{2} + 2x – 3
