Question

solve the following quaderatic equation
1. 2/3x² - 1/3x-1=0​

Answer 1

Answer:

$x = \frac{3}{2} \: \: and \: - 1$

Step-by-step explanation:

$\frac{2}{3} {x}^{2} - \frac{1}{3}x - 1 = 0$

$\frac{2 {x}^{2} - 1x - 3 }{3} = 0$

$2 {x}^{2} - 1x - 3 = 0$

$2 {x}^{2} + 2x - 3x - 3 = 0$

$2x(x + 1) - 3(x + 1) = 0$

$(2x - 3)(x + 1) = 0$

$2x - 3 = 0$

$x = \frac{3}{2}$

$x + 1 = 0$

$x = - 1$

possible values of x are 3/2 & -1
