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
