( a² - b² )x² + a²b² = 2a²bx
( a² - b²)x² - 2a²bx + a²b² = 0
a = ( a² - b²)
b = -2a²b
c = + a²b²
DELTA = ( -2a²b)² - 4 * (a²-b²) * (a²b²) = 4a⁴b² - ( 4a² - 4b² ) (a²b²) = 4a⁴b² - ( 4a⁴b² - 16a⁴b⁴ ) = 4a⁴b² - 4a⁴b² + 16a⁴b⁴ = 16a⁴b⁴ ou V(16a⁴b⁴) = +- 4a²b² *******
x= ( 2a²b +- 4a²b² ) / 2 ( a² - b² ) = ( 2a² b +- 4a²b² )/ 2( a + b) ( a - b)
x1 = 2a²b ( 1 + 2b)/ 2 ( a + b)( a - b) = a²b ( 1 + 2b) / ( a + b)(a -b)=
a²b( 1 + 2b)/(a²-b²)
x2 = ( 2a²b - 4a²b² )/ 2 ( a² - b²) = 2a²b ( ( 1 - 2b ) /2 ( a²-b²) = a²b ( 1 - 2b) / ( a²-b² )
( a² - b²)x² - 2a²bx + a²b² = 0

x2 = ( 2a²b - 4a²b² )/ 2 ( a² - b²) = 2a²b ( ( 1 - 2b ) /2 ( a²-b²) = a²b ( 1 - 2b) / ( a²-b² )
