Math Challenge 20

'
Can anyone come out the answers for A, B, C and D in the below math expression?

A2 + B2 + 2C2 = D2

The rule is that the unknowns are all integers and below 10.

Happy trying, and
don't forget that maths is interesting!

I think you can assign any integer (just below 10) you want as long as the 2 sides are equal.. :)

well one thing you can do is take A,B,C equal and take D twice of A,B or C you will get the equality correct.....
