Question

use factor theorem to determine whether x+3 is factor of x²+2x+3​

Answer 1

Answer:

In algebra, the factor theorem is a theorem linking factors and zeros of a polynomial. It is a special case of the polynomial remainder theorem. The factor theorem states that a polynomial has a factor if and only if.

Answer 2

Answer:

X + 3 is factor of given polynomial p(X)

therefore p(-3) = 0

therefore p (X) = X² + 2x - 3

p(-3) = (-3)²+2× -3 -3

= 9-6-3

= 9-9

p (-3) = 0

therefore X + 3 is factor of x² + 2x - 3
