Question

${x }^{2} + {y}^{2} = 74$
xy=35
find value of x+y

​

Answer 1

$\huge\underline\mathfrak\purple{Solution}$

xy = 35

x² + y² = 74

( x + y )² = x² + y² + 2xy

( x + y )² = 74 + 2 × 35

( x + y )² = 74 + 70 = 144

x + y = 12

Thanks!

Answer 2

Step-by-step explanation:

xy = 35

x² + y² = 74

( x + y )² = x² + y² + 2xy

( x + y )² = 74 + 2 × 35

( x + y )² = 74 + 70 = 144

x + y = 12
