Question

решите уровнерие х²- 4/ х - 2 = 0
​

Answer 1

$\displaystyle \tt \frac{x^2-4}{x-2}=0\: \: \: \: \: | \: x\ne2\\\displaystyle \tt \frac{(x-2)(x+2)}{x-2}=0\\\displaystyle \tt x+2=0\\\displaystyle \tt \underline{\bold{x=-2}}$

Answer 2

х² - 4/х - 2 = 0

х² - 4/х - 2 = 0 х ≠ 2

(х - 2)(х + 2)/х - 2 = 0

х + 2 = 0

х = - 2, х ≠ 2

х = - 2
