Question
Use binomial theorem to expand (2c + d)6
Hint:
The binomial expansion is 
, here n ≥ 0 .
We are asked to use binomial theorem to expand (2c + d)6 .
The correct answer is: values of the triangle
Step 1 of 2:
The given expression is (2c + d)6 , here x = 2c & y = d . The value of n=6, hence we would have 6+1=7 terms in the expression.
Step 2 of 2:
Substitute the values of (2c + d)6 in the binomial expression
Thus, the expansion is: 
.
Thus, the expansion is:
.The expansion of the expression can also be found using the Pascal’s triangle. But, it is necessary to remember the values of the triangle to write down the expansion.
