Just use the power rule:

$\displaystyle\int_{t=-a}^{t=a}(a^2-t^2)\,\mathrm dt=a^2t-\dfrac13t^3\bigg|_{t=-a}^{t=a}$

We also could have use the fact that the integrand is even to write

$\displaystyle\int_{t=-a}^{t=a}(a^2-t^2)\,\mathrm dt=2\int_{t=0}^{t=a}(a^2-t^2)\,\mathrm dt=2\left(a^2t-\dfrac13t^3\bigg|_{t=0}^{t=a}\right)$

I'll continue with this expression since it's easier to evaluate (if only a little):

$2a^3-\dfrac23a^3=\dfrac43a^3$

Answer:

$7k + 4( \frac{1}{4} k - 6) = 8k + 3k + 12 \\ \\ 7k + k - 24 = 11k + 12 \\ 8k - 24 = 11k + 12 \\ - 3k = 36 \\ { \boxed{ \boxed{k = - 12}}}$
