Common GMAT Data Sufficiency Myths - Part II## hello again :)

another question, when we are dealing with a quadratic and we know that only positive numbers fulfil our conditions (for instance in geometry), could we skip the calculation in this case? or is it also possible to get 2 positive solution from a quadratic ?

## Yes, it's possible to get to

Yes, it's possible to get to two positive solutions to a quadratic equation.

Take, for example, x² - 5x - 6 = 0

Factor to get: (x - 2)(x - 3) = 0

So, x = 2 or x = 3

Cheers,

Brent
