Factoring Trinomials

When factoring trinomials first make sure your equation is in simplest form. For example x^2+10x+25 , when this is done you have to figure out two numbers that add up to 10 and also multiply to 25. You can list all the common  factors until you find the correct one. For this problem 5 and 5 are the two numbers that add up to 10 and multiply to 25. After this you factor it, since there is x^2 those factor out to x and x the you just add the 5's and your answer will be (x+5)(x+5)
