Question

2nd term of (2r-3s)^12

Answer 1

Answer:

1.-12*(2r)^11 * (3s)

= -12*2048*3 r^11 s

= -73728 r^11 s

2.12C1 (2r)¹¹(-3s) = -36(2¹¹)r¹¹s = -73728r¹¹s

3.24 r - 36 s

The second term: -36 s

4.(2r-3s)^12

= (2r)^12 + 12C1 (2r)^11 (-3s)

= 2^12 r^12 + (12) 2^11 r^11 (-3) s

= 4096 r^12 - (12)(3)(2098) r^11 s

= 4096 r^12 - 73,728 r^11 s + .....

-73,728 r^11 s
