Answer:
0 and -2 are zeroes
Step-by-step explanation:
4a²+8a
4a (a+2)
4a = 0
a=0/4
a=0.
a+2=0
a=-2
0 and -2 are zeroes
RELATIONSHIP BETWEEN ZEROES AND COEFFICIENTS
sum of zeroes = -(coefficient of a)/coefficient of a²
0+(-2) = -(8)/4
0-2 = -2
-2 = -2
L.H.S. = R.H.S.
Hence verified
product of zeroes=constant term/coefficient of a²
0(-2) = 0/4
0 = 0
L.H.S. = R.H.S.
Hence verified
