$\begin{matrix}\left(1\right)\left(-3\right)=-3\\ \left(1\right)+\left(-3\right)=-2\end{matrix}$
Learn how to solve factor problems step by step online. Factor the expression (a^2-2a+-3)/(a+1). Factor the trinomial a^2-2a-3 finding two numbers that multiply to form -3 and added form -2. Thus. Simplify the fraction \frac{\left(a+1\right)\left(a-3\right)}{a+1} by a+1.
