raden · Answer

you need 2 numbers whose product is 48 and when 
these are added get 14

$$x^2 + 14x + 48$$$$=(x+a)(x+b)=x^2+ax+bx+ab=x^2+(a+b)x+ab$$
$$\qquad\qquad\qquad 14=a+b$$
$$\qquad\qquad \qquad ab=48$$
all the pairs of factors of $48$ are ;

$(\pm1)(\pm48),~(\pm2)(\pm24),~(\pm3)(\pm16),~(\pm4)(\pm12),~(\pm6)(\pm8)$

$a ~~\& ~~b$  are the factor pair that add to $14$
