Answer:

Sum of Zeroes = -4

Product of Zeroes = -9

Step-by-step explanation:

Let the polynomial be mx²+nx+c with factor (x-a)(x-b) whose zeroes are a , b where m≠0

so a+b =(-n/m) and ab = (c/m)

likewise put the values of m,n and c from polynomial x²+4x-9

so m=1 ,n=4 ,c=-9

a+b= -4/1

ab=-9/1

Hence proved
