Choose one of the techniques for factoring polynomials ( Application, use factoring to solve problems). I need an explanation on this technique (Application. Use factoring to solve problems, here is an example.
Technique- Application, use factoring to solve problems
110. Area of a sail. The area in square meters for a triangular
sail is given by A(x) = x^2 + 5x + 6.
b) If the height of the sail is x +3 meters, then what is
the length of the base of the sail?
Factorize the numerator, we will get
After canceling the common term (x+3) in numerator and denominator, we will get
A step by step easy to follow solution is provided.
