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
3+5+7=15
therefore you don’t want to affect the average so your going to want your numbers to be equal length away from 15 so there are multiple answers one answer would be
a=14
b=16
