    \[5 \cdot \cos^{2}x-5 \cdot \sin^{2}x +sinx+cosx=5\cdot(cosx+sinx)(cosx-sinx)+(sinx+cosx)\] and now \[5 \cdot \cos^{2}x-5 \cdot \sin^{2}x +sinx+cosx=5\cdot(sinx+cosx)(cosx-sinx +1)\]

    if this is confusing, put \(a=\cos(x)\) and \(b=\sin(x)\) and factor \[5a^2-5b^2+a+b\]

    it has nothing whatsoever to do with trig, but the all those trig functions will tend to confuse
