Question

2x2-5x+3=0 faça a equação.​

Answer 1

$2x^2 - 5x + 3 = 0$

$x = \dfrac{-(-5)\pm \sqrt{(-5)^2 - 4\cdot 2\cdot 3}}{2\cdot 2}$

$x = \dfrac{5\pm \sqrt{25 - 24}}{4}$

$x = \dfrac{5\pm 1}{4}$

$x_1 = \dfrac{5+ 1}{4}$

$x_1 = \dfrac{6}{4}$

$x_1 = \dfrac{3}{2}$

$x_2 = \dfrac{5- 1}{4}$

$x_2 = \dfrac{4}{4}$

$x_2 = 1$
