5) 16r^2+1369+16p^2+296r-592p-32pr

________________________________

Step-by-step explanation:

4) p2 + 15P+ 56

=p^2+(7+8)p+56

=p^2+7p+8p+56

=p(p+7)+8(p+7)

=(p+7)(p+8)

________________________________

5)(4r + 37 - 8P)^2

={(4r)+37+(-8p)}

=(4r)^2+(37)^2+(8p)^2+{2(4r)(37)}+{2(37)(-8p)}+{2(-8p)(2r)}

=16r^2+1369+16p^2+296r-592p-32pr
