Tricky Cubic Equation## isn't K's sign going to

How can we be sure that k value won't effect the choice ???

## First of all, we need not

First of all, we need not solve for k. We can find the correct answer without solving the given equation.

That said, if k = -11/3, then Quantity A = 3 + 11(-11/3) = 3 - 121/3 = -112/3

If k = -11/3, then Quantity B = 11(-11/3) - 3 = 121/3 - 3 = -130/3

Quantity A is greater (you suggested that Quantity B is greater)

## Yea really tricky. I didn't

## By far one of my most

## So I have a quick question ,

## Be careful. We can safely ADD

Be careful. We can safely ADD or SUBTRACT any value (positive or negative) from both quantities.

However, we must avoid MULTIPLYING or DIVIDING both quantities by a negative value.
