Question

. If x + y = 3, xy = 2, find the value of x3 + y3.
​

Answer 1

Answer:

according to your question x+y=3 from xy=2 ,x=2/y then put this value of x in x+y=3 then we get the value of y=√3y-2 and value of x=3-√3y-2 ,then value of x³+y³ is 27-(√3y-2)+(√3y-2) then answer is 27.

Step-by-step explanation

Answer 2

Answer:

answer is 9

Step-by-step explanation:

because the question says that x+y is 3

and xy= 2

2 is a prime number so it can only divisible by 2 and 1

so it's clear that x is 2 and y is 1 so the value of x into 3 plus y into 3 is

2 into 3 and 1 into 3 so the answer is 9
