The second term in the binomial expansion of (2r - 3s)¹² is -73728 r¹¹ s option (A) is correct.
What is an expression?
It is defined as the combination of constants and variables with mathematical operators.
It is given that:
(2r - 3s)¹²
Using nth term of the binomial expansion is:
= C (12, 2-1) (2r)¹²⁻²⁺¹ (-3s)²⁻¹
After solving
= -73728 r¹¹ s
Thus, the second term in the binomial expansion of (2r - 3s)¹² is -73728 r¹¹ s option (A) is correct.
