Question

usesfactor Theorem x+3 is a factor of X2 +2x -3 or not​

Answer 1

Answer:

x-3 is the factor of p(x)

Step-by-step explanation:

If x + 3 is a factor , then -

x + 3 = 0

x = -3

p(x) = x² + 2x - 3

If x = -3 then p(x) must be zero

p(-3) = (-3)² + 2(-3) - 3 = 0

        = 9 - 6 - 3 = 0

        = 0 = 0

Hence, x-3 is the factor of p(x)
