Answer 2

Answer:

x=1.879385 or x=−1.532089 or x=−0.347296

Step-by-step explanation:

x^2−1/x  = 3

x^2−1/x=3

Multiply all terms by x and cancel:

x^2 x−1=3x

x^3−1 = 3 x (Simplify both sides of the equation)

x^3−1−3 x=3x−3x (Subtract 3x from both sides)

x^3−3x−1=0

(Use cubic formula)

x=−1.532089,−0.347296,1.879385

Check answers. (Plug them in to make sure they work.)

x=1.879385(Works in original equation)

x=−1.532089(Works in original equation)

x=−0.347296(Works in original equation)
