f(x)=x²
f'(x)=2x f'(a)=2a
g(a) = g(0)+2a*a=a*a
g(0)= - \(a^{2} \)
g(x) = - \(a^{2} \) +2a*x
f(x)-g(x)= \(x^{2} \)-2ax+\(a^{2} \)
\( \int\limits_{0}^{a} \) \(x^{2} \)-2ax+\(a^{2}dx \)
= \( \frac{1}{3} \)\( x^{3} \)-a\( x^{2} \)+\( a^{2} \) \( \left. x \right|_0^a \)
= \( \frac{1}{3} \)\( a^{3} \)= A
