Question

factorise : 8 (3a - 2 b)² -10 (3a - 2b)

Answer 1

(3a-2b)(8-10)(3a-2b)

Answer 2

solution:-

=> 8(3a-2b)² - 10(3a - 2b)

= 8 [(3a)²-2(3a×2b)+(2b)²] -10(3a-2b)

= 8 [9a² - 12ab + 4b² ] - 10(3a - 2b)

= 72a² - 96ab + 32b² - 30a + 20 b

= ½[36 a² - 48ab + 16 b² - 15a + 10b]

i hope it helps you.
