Question

why are 4 and -1 are the zero of the polynomial p (x) = x square - 3x -4 given the reson​

Answer 1

Answer: 4 and -1 are the zero of p(x) because when substituted for x the remainder is 0.

Step-by-step explanation:

p (x) = 4 square - 3(4) - 4

      = 16 - 12 - 4

      = 4 - 4

      = 0

p (x) = -1 square - 3(-1) - 4

      = 1 + 3 - 4

      = 4 - 4

      = 0
