Question

Решите уравнение4х² - 8х + 3 = 0

Answer 1

$4 {x}^{2} - 8x + 3 = 0 \\ \\ 4 {x}^{2} - 8x = - 3 \\ (2x) {}^{2} - 2 \times 2 \times 2x = - 3 \\ (2x) {}^{2} - 2 \times 2 \times 2x + 4 = - 3 + 4 \\ (2x - 2) {}^{2} = 1 \\ 2x - 2 = 1 \: \: ili \: \: \: 2x - 2 = - 1 \\ \\ x1 = \frac{3}{2} \\ x2 = \frac{1}{2}$
