Hasil dari (2p + 3q)² - (3p - 5q)² beserta CARANYA yaaaa.. a. 13p² - 2pq + 34q² b. 13p² - 4pq + 34q² c. -5p² - 28pq - 16q² d. -5p² + 42pq - 16q²

Pembahasan : D

(2p+3q)2 – (3p-5q)2 = (2p)2+2(2p x 3q) + (3q)2 – (3p)2 – 2(3p x 5q) (-5q)2

                                        =( 4p2+12pq+9q2) – (9p2-30pq+25q2)

                                         = -5p2+42pq – 16 q2
