Question

If x²+y²=14 and xy = 2½, find the value of x-y with an example of copy photo​

Answer 1

Step-by-step explanation:

( x-y )^²= x^²+y^²-2xy

= 14-2(√2)

x-y. = ( 14-√8 )^½

Answer 2

Answer:

Step-by-step explanation:

Given that,

x² + y² = 14 and xy = √2

we know that,

( x - y )² = x² + y² - 2xy

= 14 - 2√2

( x - y ) = √( 14 - 2√2 )
