Answer 2

Answer:

Step-by-step explanation:

actual qn is :

If x²+y=37 and xy=6 find

1 .x+y

2. x-y

3. x²-y²

*********************

x²+y²=37, xy=6,

(i) x²+y²+2xy=37+2xy

(x+y)²=37+2*6

(x+y)²=49

x+y= ±7

**************

(ii) (x-y)²=x²+y²-2xy

=37-2*6

=37-12=25

x-y=±5

(iii) x²-y²

=(x+y) (x+y)

=5*7=35
