Question

x²+y²=29,xy=2 find the value of x-y​

Answer 1

Answer:

your answer

Step-by-step explanation:

we know that,

x²+y²-2xy = (x-y)²

so , now substitute the given values in equation

we get , => 29-2(2) = (x-y)²

=> 29-4 = (x-y)²

=> 25 = (x-y)²

=> √25 = (x-y)

=> 5 = (x-y)

=> -5 = (x-y)

hope this helps

Answer 2

Answer:

Step-by-step explanation:

xy = 2

=>-xy = -2

=>-2xy = -4

so, x^2 + y^2 -2xy = 29-4

=> (x-y)^2 = 25

=> x-y = 5
