Question

( (x+y)(x+z)=a^{2} )
( 7 cdot x^{2}+x y+y z+x z=a^{2} )
( (y+2)(x+y)=b^{2} )
( Rightarrow g^{2}+x z+y z+z x=b^{2} )
( (x+2)(y+2)=c^{2} )
( z^{2}+y z+z x+x y=c^{2} )
11
( 0+mathbb{1 1}+(11)^{prime} )
( x^{2}+y^{2}+z^{2}+z(x y+y z+z x)=a^{2}+b^{2}+c )
a ( (x+y+z)^{2}=a^{2}+b^{2}+c^{2} )
( Rightarrow quad x+y+z=sqrt{a^{2}+b^{2}+c^{2}} )

# If exty) (2+2) = a? (Y+z) Caty)= b? (2+2) (y + 2) =/? then x,y,2=9

Solution
