Question

find value of x and y​

Answer 1

Answer:

Step-by-step explanation:

p(x-y) + q(x+y)  =  0                               ....1

p(x+y) - q(x-y)  =  2(p²+q²)                     ....2

add eq 1 and eq 2 we get

p(x-y) + q(x+y)  =  0                            

p(x+y) - q(x-y)  =  2(p²+q²)  

-          +               -            

px - py - px - py + qx + qy + qx - qy = -2p² - 2q²

-2py + 2qx = -2p² - 2q²

py - qx = p² + q²
