Question

given (x+y)=13 and xy=22, find the value of x²+y².

Answer 1

225

Answer:

let's first find the values of x and y

the sum of x and y should be 13

and if we multiply both x and y then we should get 22

Let the x = 11

Let the x = 11y = 2

sum

$x+y= 13$

$11 + 2 = 13$

Multiply

$x \times y = 22$

so we got the value of x and y as 11 and 2 respectively

now let's find out the value of

${x}^{2} + {y}^{2}$

${11}^{2} + {2}^{2}$

$121 + 4$

$125$
