(3p - 2)(3p - 2) - (p - 1)(p - 1)
(3p(3p) + 3p(-2) - 2(3p) - 2(-2)) - (p(p) + p(-1) - 1(p) - 1(-1))
(9p² - 6p - 6p + 4) - (p² - p - p + 1)
(9p² - 12p + 4) - (p² - 2p + 1)
9p² - 12p + 4 - p² + 2p - 1
9p² - p² - 12p + 2p + 4 - 1
8p² - 10p + 3
8p² - 10p + 3
8p² - 6p - 4p + 3
2p(4p - 3) - 1(4p - 3)
(2p - 1)(4p - 3)
= (9p+4)-(2p+1)
= 18p²+9p-8p+4
=18p²+p+4
kalau salah maaf
