Question

Given that x - y = 5 and xy = -6/1/2,
find the value of x² + y².​

Answer 1

Answer:

• 24

Step-by-step explanation:

• (x - y)² = x² + y² - 2xy
• x² + y² = (x - y)² + 2xy

Substitute given values

• x² + y²  = 5² + 2(-6/12) = 25 - 1 = 24

Answer 2

Answer:

Given that x - y = 5 and xy = -6/1/2,

Step-by-step explanation:

the value of x² + y².

=(x-y)²+2xy=5²+2×[-6 1/2]=25-13=12 is your answer
