Solve: 4x^-2 - 3x^-1 - 1 = 0

X = 1 or X = - 4

Step-by-step explanation:

Let's solve your equation step-by-step.

4x-2-3x-1-1=0

-x2-3x+4

x2

=0

Step 1: Multiply both sides by x^2.

-x2-3x+4=0

(-x+1) (x+4) = 0 (Factor left side of equation)

-x+1=0 or x+4=0 (Set factors equal to 0)

x=1 or x=-4

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

x=1 (Works in original equation)

x=-4 (Works in original equation)
