Question

Find the value (x+y)² if x²-y²=-12 and y-x=2

Answer 1

Answer:

36

Step-by-step explanation:

given

y-x = 2

=> x - y = -2................(1)

x²-y²= -12

=> (x+y) (x-y) = -12

=> ( x+y) (-2) = -12. ........from(1)

=> (x+y) = -12/-2 = +6

squaring on both sides

=> ( x+y)² = 36

hope this helps you

Answer 2

================================

Answer :

(x+y)² = 36

Step-by-step explanation :

$(x+y)^2=?\\\\y-x=2\\\\=>x-y=-2...(1)\\\\x^2-y^2=-12\\\\=>(x+y)(x-y)=-12\\\\=>(x+y)(-2)=-12\\\\=>(x+y)=6$

Squaring on both sides , we get ,

=> (x+y)² = 36
