Question

1) (x - 2)² - (3 - x)² = 0;​

Answer 1

Ответ:

5/2

Объяснение:

х² - 4х + 4 -(9-6х+х²) = 0

х² -4х +4 - 9 + 6х - х²= 2

2х-5= 0

2х=5

Answer 2

***

$\displaystyle \bf \Big(x-2\Big)^2-\Big(3-x\Big)^2=0\\\\\\\\ x^2-4x+4-\Big(9-6x+x^2\Big)=0\\\\x^2-4x+4-9+6x-x^2=0\\\\2x-5=0\\\\2x=5\\\\x=\frac{5}{2} \\\\x=2.5$
