x2+14x+48 = (x+_)(x+_)

 

You need to look for two numbers 

that multiply to 48

and add to 14

 

Since everything is positive the numbers will both be positive.

lets see, look at the muliply first, 

   12*4 =48 but 12+4=16, that is no good.

    6*8=48  and  6+8=14  wonderful

 

so tha answer is

(x+6)(x+8)
