Respuesta :
(A + B)3's binomial expansion has (D) 1, 3, 3, 1 coefficients.
What are coefficients?
A coefficient in mathematics is a multiplicative factor in a polynomial term, a series term, or an expression.
It is typically a number, but it can also be any expression.
They may also be referred to as parameters if the coefficients are variables in and of themselves.
A coefficient is, in other words, the numerical factor of a term that contains both constants and variables.
For instance, the coefficient in the expression 2x is 2.
So, we have: (a + b)3
Since we have nothing before (a + b)3.
Then the coefficient will be 1 here.
If we have 3 after (a + b) then the coefficient will be 3.
Therefore, (A + B)3's binomial expansion has (D) 1, 3, 3, 1 coefficients.
