Question

if X – Y =8 and XY =11 find the value of​

Answer 1

Answer:

we have X – Y =8 and XY =11

Step-by-step explanation:

take left hand side

solving it we get

x - y = 8

x = 8 + y

now put value of x = 8 + y in xy = 11

we get

(8 + y ) y = 11

8y + y2 = 11

sorry I don't know the proper answer

Answer 2

Answer:

I guess the question is like this

If x-y=8 and xy=11,find the value of

(x²+y²)

(x²+y²) =(x-y) ²+2xy

(Putting the values)

(x²+y²)= 8²+2×11

(x²+y²)=64+22

(x²+y²)=86
