If x+1/x=5, then what is the value of x⁴-1/x⁴?

x=1, then the value is 0

x=5, then the value is 624/625

Step-by-step explanation:

Instead of x, we plugin 1.

Instead of x, we plugin 5.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
