which can be factorized as
$$(\sin x + \cos x - \sin x \cos x)(\sin x + \cos x + \sin x \cos x)=0$$
you effectively introduced another equation $\sin x + \cos x =- \sin x \cos x$ in the process beside the original one $\sin x + \co... | Using auxiliary angle, we first change the equation
$$
\sin x+\cos x=\sin x \cos x \tag\*{(\*)}
$$
equivalently to
$$
\sqrt{2} \cos \left(x-\frac{\pi}{4}\right)= \frac{\sin 2 x}{2}
$$
Putting $y=x-\dfrac{\pi}{4} $ gives a quadratic equation in $\cos y $
$$
\sqrt{2} \cos y=\frac{1}{2}\left(2 \cos ^{2} y-1\right)

This allows a `b` at the start and then at least one `A`, or some `A`s at the start and optionally a `b` at the end. This covers all the possibilities and is slightly faster than the accepted answer in the case that it doesn't match as only one of the two options needs to be tested (as... | ```

why doesn't that work? |
