Question

Simplify (x+y)³ and (x+y)³ diffrently can you solve them​​

Answer 1

Answer:

Step-by-step explanation:

1. (x +y)^3 = (x +  y)(x + y)^2

= (x + y)(x^2 + 2xy + y^2)

= x^3 + 2x^2y + xy^2 + x2y  + 2xy^2 + y^3

= x^3 + 3x^2y + 3xy^2 + y^3.

2, Using Pascal's Triangle

                     1

                1          1

        1           2          1

1          3            3            3

(x + y)^3 = x^3 + 3x^2y + 3xy^2 + y^3.
