Solve for by factoring:
We start by using algebra to get a zero on the right and everything else on the left:
Now we factor the left-hand side. I'll use the slide-and-divide method. See this sheet for reference.
In order to factor, we must find two numbers whose product is and whose sum is . Those numbers are and . Therefore, the factorization of the left-hand side is given by
Now we solve the equation by setting the factors equal to zero.
