Question

if x = 2+ 3i and y = 2 - 3i,find the value of (x^2 + xy + y^2)/(x^2-xy+y^2)​

Answer 1

Answer:

answer is - 3/23.

Step-by-step explanation:

x^2=4+12i-9=12i-5

y^2=4-12i-9=-12i-5

so x^2+y^2=-10

and xy= 4+9=13

so (x^2 + xy + y^2)/(x^2-xy+y^2)

= - 3/23 .

Answer 2

Answer:

answer is - 3/23.

Step-by-step explanation:

x^2=4+12i-9=12i-5

y^2=4-12i-9=-12i-5

so x^2+y^2=-10

and xy= 4+9=13

so (x^2 + xy + y^2)/(x^2-xy+y^2)

= - 3/23 .
