Answer 1

Answer:

6

Step-by-step explanation:

Hey there...!!

• I hope your question is like this:-

${x}^{2} + {y}^{2} + x - y$

• If it is, then the answer is as follows on substituting the value of X as -1 and Y as 3:-

${x}^{2} + {y}^{2} + x - y \\ = {( - 1)}^{2} + {(3)}^{2} + ( - 1) - (3) \\ = 1 + 9 - 1 - 3 \\ = 6$

hope this helps...!!
