(b) a² + 2b² from 3b² - 4a²
(c) 5x²y - 3xy² from – 2x²y + 4xy²
(d) 2a - 3b + 5 from 5a - b - 2
(e) p + q - r from - p -q - r
(f) a³ + b³ - 3abc from - a³ + b³ + 3abc ​

Answer 1

Step-by-step explanation:

$\sf \implies(3x + 2y) - (2x + 3y)$

$\sf\red{ \implies3x+2y−2x−3y}$

$\tt \pink{ \implies \: x−y}$
