1) acknowledge the rule that anything that’s outside of the bracket applies to EVERYTHING inside of the bracket
2)apply the rule: (A-6)^2
we have the expression

Evaluate for x=-4/5 and y=1/3
substitute the values of x and y in the given expression

the answer is 32/15
The answer to the question
<span> a) F' = 6 sin(x^2) = 0
x^2 = pi
x = sqrt(pi)
b) Fmax = F(1) + integral [1, pi] f(x) dx = 9.7743 </span>
the question is not so clear
is it (x+3)/3 or what you have written is correct
