How can I take derivative $$\frac{d}{dA}(x - Ab)(x - Ab)^T$$

where $x$ and $b$ are known vectors of the same size and matrix $A$ is symmetric and positive-definite?

**Update**:
This expression could be expanded as $xx^T - Abx^T - xb^TA^T + Abb^TA^T$. Taking derivative will get $-2bx^T + \frac{d}{dA}Abb^TA^T$, so question now is how to calculate the last term.
