How do you integrate $\int \frac{\cos (4 x)}{\cos (x)} d x$
I tried using trigonometric formulas for turning it into $2 \int \frac{\cos^{2} (2 x)}{\cos (x)} d x - \int \frac{1}{\cos (x)} d x$ and can solve the second one, but still no idea of how to proceed with $\int \frac{\cos^{2} (2 x)}{\cos (x)} d x$ .

If $\cos^{6} (x) + \sin^{4} (x) = 1$ find x if $x \in [0, \frac{π}{2}]$
My attempt:
$\cos^{6} (x) + \sin^{4} (x) = 1$
$\cos^{6} (x) + {(1 - \cos^{2} (x))}^{2} = 1$
$\cos^{6} (x) + 1 - 2 \cos^{2} (x) + \cos^{4} (x) = 1$
$\cos^{6} (x) + \cos^{4} (x) - 2 \cos^{2} (x) = 0$
