Question

The product of two zeros of a polynomial p(x)
is -3.
p(x) = x3 + 3x2
CN
- 15
Find the third zero.​

Answer 1

Step-by-step explanation:

Given that

p(x)= x³-3x²-15

$\alpha \beta = - 3$

we know that alpha× beta× gama = -d/a

( -3)× gama = -(-15)/1

=> gama = 15/-3

=> gama = -5

Therefore the third zero is -5
