Question

Write the binomial expansion of
(x+y)⁴⁸
please solve ​

Answer 1

Answer:

Exponents of (a+b)

We will use the simple binomial a+b, but it could be any binomial.

(a+b)2 = (a+b)(a+b) = a2 + 2ab + b2

(a+b)3 = (a2 + 2ab + b2)(a+b) = a3 + 3a2b + 3ab2 + b3

a3 + 3a2b + 3ab2 + b3

Now, notice the exponents of a. ...

Likewise the exponents of b go upwards: 0, 1, 2, 3:
