Question

if (n+y)=10 and xy=12 find the value if x^2y^2
​

Answer 1

Answer:

ake any equation and try to find x and y value first

I take first equation.

x+y=10

now try to get x and y values first,

x=10-y and y=10-x

Replace the x and y values in second of the given equation

i.e x-y=12

So now after changing the x values the equation would be

x-y=12.........(2)

(10-y)-y=12

10-2y=12

-2y=12-10

-2y=2

-y=2/2

-y=1

y=-1

So finally y=-1 now put y value in any of the equation

I take second equation again

x-y=12.........(2 equation)

x-(-1)=12
