What’s the non-permissible value for x^2-x-2

x = -1 and x = 2 are non-permissible

Step-by-step explanation:

for rational equations, the denominator can't equal zero, so find the zeroes of the equation, those will be the non-permissible numbers...

take the denominator and set it equal to zero, then solve...

x² - x - 2 = 0

(x - 2)(x + 1) = 0

so

x - 2 = 0

    x = 2

and

x + 1 = 0

   x = -1

Either of these values make the denominator equal zero, so they are not part of the domain of the function (non-permissible numbers)

*i think

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
