Question 1173127: 1. 1. Solve the quadratic equation
x^2 − 2x − 3 = 0.
2. Factor 3x^3 − 12x
3. Rationalize 5/3\sqrt{x} Found 2 solutions by Boreal, ikleyn:Answer by Boreal(15235) (Show Source):

factor out the common factors 3 and x
3x(x^2-4). Now there is a difference of squares, which may be factored
3x(x+2(x-2)

The last isn't clear.
(5/3)/sqrt(x)? If that is it multiply top and bottom by sqrt (x) for (5/3) sqrt(x)/x
If it is 5/(3 sqrt(x)), multiply top and bottom by sqrt(x) to get 5sqrt(x)/3x
