Answer:
22/5
Step-by-step explanation:
Because
a= any expression for a
and B = any expression for b
Therefore b and a are both exactly negative (By Calculation)
But since they are zeroes for the same value
i.e; 2×2-5x+7= 4+7-5x= 11-5x
But since a and B are zero ,
putting anyone of them we get 0
Thus, 11-5x= 0
=> x= 11/5
Hence either one of a and B is zero and one is X
Therefore, 2a+2b=22/5
