Answer:

  • No

Step-by-step explanation:

Let's assume (x + 5) is the factor of f(x) = x^3 − 4x^2 + 3x + 7

then f(-5) should be equal to zero. Verifying:

  • f(-5) =
  • (-5)^3 - 4(-5)^2 +3(-5) + 7 =
  • -125 - 100 - 15 + 7 =
  • -233

Since -233 ≠ 0, the statement is false, so (x + 5) is not a factor of given polynomial
