Let x be an integer that satisfies x^4 + 24 = 105. what is the value of x^2 - 24?

-15

Step-by-step explanation:

+ 24 = 105

subtract 24 from both sides of the equation .

= 105 - 24

= 81

find the fourth root of both sides

x = 3

Therefore : substitute x = 3 to find the value of

- 24  =   - 24

= 9 - 24

= - 15

x = 3 ± √(5+y)
