Question

решите пожалуйста,2х²+ 3 х - 5 = 0​

Answer 1

Ответ:

2х²+3х-5=0

2х²+5х-2х=0

х×(2х+5)-(2х+5)=0

(2х+5)×(х-1)=0

х-1=0

х=1

Answer 2

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

$2x {}^{2} + 5x - 2x - 5 = 0$

$x \times (2x + 5) - (2x + 5) = 0$

$(2x + 5) \times (x - 1) = 0$

$2x + 5 = 0$

$x - 1 = 0$

$x = - \frac{5}{2}$

$x = 1$

$x1 = - \frac{5}{2}$

$x2 = 1$
