Question

4. If r = 0, y = -2, find the value of the following expression.
(x+y)³-2xy+y²
​

Answer 1

Answer:

-4

Step-by-step explanation:

Given, x = 0 and y = -2

Substituting the values, we get,

= ( 0 - 2 )³ - 2 × (0) × (-2) + (-2)²

= -8 - 0 + 4 = -4

Answer 2

Answer:

that's 0 but you have to write x not r.
