Question

(2х-1,2)(3х-0,3)=0 реш.уравнение

Answer 1

(2х-1,2)(3х-0,3)=0
$(2x - frac{6}{5} )(3x - frac{3}{10} ) = 0$

$2x - frac{6}{5} = 0$

$2x = frac{6}{5}$

$x1= frac{3}{5}$

$3x - frac{3}{10} = 0$

$x2 = frac{1}{10}$

Ответ:
$x1 = frac{3}{5}$

$x2 = frac{1}{10}$

Answer 2

(2х-1,2)(3х-0,3)=0

6х^2-0,6х-3,6х+0,36=0

6х^2-4,2х+0,36=0

Д=17,64-8,64=9

Х1,2=4,2±3/12

Х1=4,2+3/12=0,6

Х2=4,2-3/12=0,1
