Question

X^-2 - x^-1 - 6 =0
solve each equation (hint: they are quadratic in form)

Answer 1

x−2−x−1−6=0

−6x2−x+1 x2 =0

Step 1: Multiply both sides by x^2.

−6x2−x+1=0

(−3x+1)(2x+1)=0(Factor left side of equation)

−3x+1=0 or 2x+1=0(Set factors equal to 0)

x= 1 3 or x= −1 2

The answer is: x=1/3 or x=-1/2
