Answer:
The first one
Step-by-step explanation:
x^(2) +7x -8
x^(2) +7x +7/2^(2) +-1*(7/2)^2+-8 Complete the square
x+7/2^(2) +-1 x 7/2^(2) +-8 Use the binomial formula
x+7/2^(2) +1 x -81/4 simplify
1(x+7/2)^2+1 x -81/4

Answer:
(0,2)
Step-by-step explanation:
We have to find the expansion of 
We will use binomial expansion to expand the given expression, which states that the expression 
is expanded as :
Now expanding we get,
So, the variables are 
, 
, 
, ![a^{8} , [tex] ab^{7}](https://tex.z-dn.net/?f=%20a%5E%7B8%7D%20%20%2C%20%5Btex%5D%20ab%5E%7B7%7D%20)
