(7p-5r)^2 +6p +8q -10r + (4q+5r-3p)^2
Remember there isn’t any cookie cutter for (a+b+c)^2
So let’s do some assumptions
Let (4q +5r) = a
3p = b
(a-b)^2 = [(4q+5r) ^2 - (3p)^2]
= 16q^2 + 25r^2 - 40qr - 9q^2
= 49p^2 - 70pr + 25 r^2 + 6p+8q -10r + 16q^2 +25r^2 -40qr -9q^2
= Combine like terms
= 49p^2 + 50r^2 + 7q^2 - 70pr -40qr +6q + 8q -10 r
