Answer is c) 128
I added the step by step process in the pic attached, I don't know how to explain it very well but you can use binomial theorem for (3x-1)^7
Then you can add up all the coefficients of the calculated values as the question mentions afterwards a^7 + a^6 +..... which means it only wants you to add up the coefficients of the consecutive x terms, otherwise it would say a^7x^7 + a^6x^6 +..... and so on
Hope this helps :)

Answer:
Step-by-step explanation:
the quadratic function should be as follows:
Now let's confirm that the zeros of the function are 0 and 8
Therefore we can see that if x = 0
the equation is fulfilled
And we also have
for this expresion to be equal to zero:
thus, if x = 8
the equation is also fulfilled
The zeros of the quadratic function are 0 and 8.
