Answer:
730 1/3
Step-by-step explanation:
It should be written as:
2(a+b)+ (a+b)/6+(a+b)^2-2, so that the quantity a + b is divided by 6 and not just b.
Hence, we have that
2(a+b)+ (a+b)/6+(a+b)^2-2 =
2(26) + 26/6 + 26^2 - 2 =
52 + 13/3 + 676 - 2 =
52 + 4 1/3 + 674 =
1/3 + 56 + 674 =
1/3 + 730 =
750 1/3
