If x 1 and x 2 be two integers such that x 1 ≠ 0 , x 2 ≠ 0 and - 2 < x 1 , x 2 < 2 , then find the values of x 1 + x 2 .

Given, x 1 and x 2 be two integers such that x 1 ≠ 0 , x 2 ≠ 0 and - 2 < x 1 , x 2 < 2 We need to find the values of x 1 + x 2 . Since, - 2 < x 1 , x 2 < 2 , so the values of x 1 , x 2 = - 1 , 1 If x 1 = - 1 , x 2 = - 1 ⇒ x 1 + x 2 = - 1 + - 1 = - 2 x 1 = - 1 , x 2 = 1 ⇒ x 1 + x 2 = - 1 + 1 = 0 x 1 = 1 , x 2 = 1 ⇒ x 1 + x 2 = 1 + 1 = 2 Hence, the required values of x 1 + x 2 are - 2 , 0 , 2 .

If x 1 and x 2 be two integers such that x 1 ≠ 0 , x 2 ≠ 0 and - 2 < x 1 , x 2 < 2 , then find the values of x 1 - x 2 .

Given, x 1 and x 2 be two integers such that x 1 ≠ 0 , x 2 ≠ 0 and - 2 < x 1 , x 2 < 2 We need to find the values of x 1 - x 2 . Since, - 2 < x 1 , x 2 < 2 , so the values of x 1 , x 2 = - 1 , 1 If x 1 = - 1 , x 2 = - 1 ⇒ x 1 - x 2 = - 1 - - 1 = 0 x 1 = - 1 , x 2 = 1 ⇒ x 1 - x 2 = - 1 - 1 = - 2 x 1 = 1 , x 2 = 1 ⇒ x 1 - x 2 = 1 - 1 = 0 x 1 = 1 , x 2 = - 1 ⇒ x 1 - x 2 = 1 - - 1 = 2 Hence, the required values of x 1 - x 2 are - 2 , 0 , 2 .

If x 1 and x 2 be two integers such that x 1 ≠ 0 , x 2 ≠ 0 and - 2 < x 1 , x 2 < 2 , then find the values of x 1 x 2 .

Given, x 1 and x 2 be two integers such that x 1 ≠ 0 , x 2 ≠ 0 and - 2 < x 1 , x 2 < 2 We need to find the values of x 1 x 2 . Since, - 2 < x 1 , x 2 < 2 , so the values of x 1 , x 2 = - 1 , 1 If x 1 = - 1 , x 2 = - 1 ⇒ x 1 x 2 = - 1 × - 1 = 1 x 1 = - 1 , x 2 = 1 ⇒ x 1 x 2 = - 1 × 1 = - 1 x 1 = 1 , x 2 = 1 ⇒ x 1 x 2 = 1 × 1 = 1 Hence, the required values of x 1 x 2 are - 1 , 1 .
