Find two factors of the last number that add up to the middle number.
a) two factors of 16 that add to 10: 8 and 2. Because 8x2=16 and 8+2=10. then do this:
(x+8)(x+2)
b) (x+4)(x+3)
c) (x+12)(x+1)

Thanks for the question!
mx + nx = p
Group them with x as the GCF
x(m +n) = p
Divide both sides by m+n
x = p/m+n
Hope this helps!
