( 10x) ^2 = (3x-1) ^2 + ( 10x-2) ^2
100 x^2 = 9 x^2 +1 -6x + 100x^2 +4-40 X
0 = 9 x^2 -46x +5
9x^2 - 45 X -x +5 =0
9x ( x-5) -1 ( x-5) = 0
( x-5) ( 9x-1) = 0
either X= 5 or 1/9
100 x^2 = 9 x^2 +1 -6x + 100x^2 +4-40 X
0 = 9 x^2 -46x +5
9x^2 - 45 X -x +5 =0
9x ( x-5) -1 ( x-5) = 0
( x-5) ( 9x-1) = 0
either X= 5 or 1/9
