Write the following cubes in expanded form: (i) (2x+1)(ii) (2a - 3b)

1.	Write the following cubes in expanded form: (i) (2x+1)(ii) (2a - 3b)7. Evaluate the following using suitable identities:(i) (99)(i) (102)(iii) (998)8. Factorise each of the following:(1) 8a+b+12a+b + 6ab?(ii) 8a-b?-12a+b+(iii) 27 -125a' - 135a + 225a?(iv) 64a - 275 - 1440(v) 27p' - 2167 P P9. Verify: (i).x + y = (x + y) (x2 - xy + y) (in) r-y' = (x - y) (r +10. Factorise each of the following:(i) 27y + 1252 (ii) 64m - 343n[Hint : See Question 9.1
Answer» tion:ALOHA !❤️(2x+1)³We KNOW the formula,.(a+b)³=a³-3a²b-3ab²-b³So,(2x)³-3.(2x)².(1)-3(2x).(1)²-(1)³=8x³-12x²-6x-1Hope it will help you@ SWEETY Adihya←(>▽<)ﾉ
