Question

If (x - y) = 13 and xy = -5, then find the value of 1/3(x^2 + y^2)

plzzz gave me right solution step by step. it is very urgent. I will really mark your answer as brainlist. ​

Answer 1

Answer:

53

Step-by-step explanation:

(x-y)^2 = 13^2

x^2 + y^2 - 2xy = 169

Substituting xy by -5

x^2 + y^2 - (2×-5) = 169

x^2 + y^2 + 10 = 169

x^2 + y^2 = 169 - 10

x^2 + y^2 = 159

1/3(x^2 + y^2) = 1/3 × 159

1/3(x^2 + y^2) = 53
