X²+2xy+y²=144, (x+y)³?​

The value of (x + y)³ is 1728.

Step-by-step explanation:

First, you have to find the value of x + y :

x² + 2xy + y² = 144

x² + xy + xy + y² = 144

x(x + y) + y(x + y) = 144

(x + y)(x + y) = 144

(x + y)² = 144

x + y = √144

x + y = 12

Next, the value of (x + y)³ :

(x + y) = 12³ = 1728

(x+y)³=1728

Step-by-step explanation:

(x+y)²=144=12²

(x+y)³=12*12*12=1728
