  1. Answer:

    (x+3)(x+7)

    Step-by-step explanation:

    To factor a trinomial in the form Ax^2 + Bx + C when the A = 1.  You need to find the factors of C that when added or subtracted will give you B.  

    Factors of 21 are either 1,21 or 3,7.  Since +3 and +7 will give you 10 then those will be the two factors you will use.

    Factoring x^2+10x+21 will give you (x+3)(x+7)
