Aus Online Mathematik Brückenkurs 1
In this case, we see that the left-hand side contains the factor \displaystyle x+3, which we can take out to obtain
This rewriting of the equation results in the new equation
which has the solutions \displaystyle x=-3 and \displaystyle x=8\,.
We check the solution \displaystyle x=8 by substituting it into the equation,
