Реши квадратное уравнение 2 (4x-16) 2-8 (4x-16) + 6=0

2 (4x-16) 2-8 (4x-16) + 6=0

2 ((4x-16) ^2-4 (4x-16) + 3) = 0

2 (16x^2-128x+256-16x+64+3) = 0

2 (16x^2-144x+323) = 0

2 (16x^2-68x-76x+323) = 0

2 (4x * (4x-17) - 19 (4x-17)) = 0

(4x-19) * (4x-17) = 0

4x-19=0. x = (19/4)

4x-17=0. x = (17/4)
