Hi friend,

(3-x)^2+3^2=6^2+x^2
[Identity-2 (a-b)^2=a^2-2ab+b^2
(3)^2-2*3*x+(x)^2+3^2=6^2+x^2
9-2*3*x+x^2=36+x^2
9-6x+x^2+9=36+x^2
9+9-6x+x^2=36+x^2
18-6x+x^2=36+x^2
-6x+x^2=36-18+x^2
-6x+x^2=18+x^2
-6x=18+x^2-x^2
-6x=18
x=18/-6
x=-2

Hope it helped you..................and if not helpful report it I don't have any problem.............
