Question

решите уровнерие х²- 4/ х - 2 = 0
​

Answer 1

$displaystyle tt frac{x^2-4}{x-2}=0: : : : : | : xne2\displaystyle tt frac{(x-2)(x+2)}{x-2}=0\displaystyle tt x+2=0\displaystyle tt underline{bold{x=-2}}$

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
