Step-by-step explanation:
Answer:
The coefficients are;
1,28,378 and 3,276
Step-by-step explanation:
For the binomial expansion, when we talk of the coefficients, we mean the whole numbers that stands before the alphabets
For example, the coefficient of x in 2x is 2
Back to the question;
(x + y)^28
= 28C0 x^28y^0 + 28C1 X^27y^1 + 28C2 x^26y^2 + 28C3 x^25y^3 + ..........
So the coefficients we are looking for are;
28C0 = 1
28C1 = 28
28C2 = 378
28C3 = 3,276
Kindly note that 28C0 is read as 28 combination zero and so on
From the answer, let's assume that you can only use each number once.
So there are four slots.
_ _ _ _
For the first slot, you have a possibility of 9 numbers.
9 _ _ _
Now for the second slot, you have the possibility of 8 numbers.
9 8 _ _
Now for the third slot, you have the possibility of 7 numbers.
9 8 7 _
Now for the last slot, you have the possibility of 6 numbers.
9 8 7 6
Now multiply these numbers together and you should get 3,024.
