Answer: x^2 - x - 56
Step-by-step explanation:
Oe zero is 8 and the product of zeroes is -56. So the second zero is -56/8= -7
Method 1
Sum of zeroes= 8 + -7 = 1
Product= -56
Do polynomial is x^2 - sum*x + product
= x^2 - x - 56
Method 2
Since 8 and -7 are zeroes, the polynomial is
(x - 8)(x - -7)=(x-8)(x+7)
= x^2 - x - 56
