Question

if (x-y)=6 and xy=14 find the value of (x+y)​

Answer 1

Answer:

116 is correct answer

Answer 2

SOLUTION

GIVEN

x - y = 6 & xy = 14

TO DETERMINE

The value of x + y

EVALUATION

Here it is given that x - y = 6 & xy = 14

Now

$\sf{ {(x + y)}^{2} = {(x - y)}^{2} + 4xy}$

$\sf{ \implies \: {(x + y)}^{2} = {(6)}^{2} + 4 \times 14}$

$\sf{ \implies \: {(x + y)}^{2} = 36 + 56}$

$\sf{ \implies \: {(x + y)}^{2} = 92}$

$\sf{ \implies \: {(x + y)}^{} = \sqrt{92} }$
