#1**+1 **

First one

Notice that the last term has to be "+25"

So....we can eliminate A and D because their final terms will yield " -25"

Since all therr terms of the polynomial are positive, the factors will only have a "+" involved

Look at C

(2x + 5) (x + 5) = 2x^2 + 5x + 10x + 25 = 2x^2 + 15x + 25

So....this is the correct choice......
