Using pascal’s triangle, determine the first four terms of the expanded expression (x + y)4.

Step-by-step explanation:

Given is an algebraic expression raised to power 4

Let us write 4 rows of Pascal triangle

           1

      1    2    1

1         3    3     1

1    4    6     4    1

Thus we find coefficients as 1,4,6,4,1 and x will be having reduced powers while y will have increasing powers.

Hence expansion would be

{3 + i, 3 - i, 3, -1}
