Помогите плиз №1 5x^2=2+3x №2 6x^2-1=5x

1. 5x^2 - 3x - 2 = 0D = 9 + 4 * 5 * 2 = 49, корень(D) = 7x(1) = (3 + 7) / (2 * 5) = 10 / 10 = 1x(2) = (3 - 7) / (2 * 5) = -4 / 10 = -0,4Ответ: -0,4; 1.2. 6x^2 - 5x - 1 = 0D = 25 + 24 = 49, корень(D) = 7x(1) = (5 + 7) / (2 * 6) = 12 / 12 = 1x(2) = (5 - 7) / (2 * 6) = -2 / 12 = - 1/6Ответ: - 1/6; 1.
