Question

(x-y) (x+y) =(2,8) then find x,y​

Answer 1

Answer:

= (2-8) (2+8)

=(-6) (10)

=(-60)

Answer 2

Answer:

x = 1.7, y = 0.3

Step-by-step explanation:

Given that, (x + y)(x - y) = 2.8

One possibility is:

x + y = 2 and

x - y = 1.4

Adding, 2x = 3.4, =>x=3.4/2 = 1.7

and y = 2 - x = 2 - 1.7 = 0.3
