Question

(x+5)(x-5) find each product

Answer 1

Hi


It is simple if you use FOIL


(x+5)(x-5) = x*x - 5*x + 5*x - 5*5
                 = x^2 - 5x + 5x  - 25



So you would reach:


$(x+5)(x-5)=x^2 - 25$



Here is the answer.... but you ought to understand how it comes



If you still need help, just let me know.
