Question

If x square + y square = 17 and xy = 4 then find the value of x/y + y/x

Answer 1

1.x^2+y^2=17 and 2. xy=4

• divide equation 1 by 2
• u get
• (x^2) /xy+ (y^2)/xy =17/4
• x/y+y/x=17/4 which is required

Answer 2

Answer:

Hi there! Here's your answer:

Step-by-step explanation:

x² + y² = 17

xy = 4

Dividing the equations,

(x² + y²) / xy = 17/4

x²/xy + y²/xy = 17/4

x/y + y/x = 17/4.
