Is it possible to factor #y=9x^2 - 17x - 85#? If so, what are the factors?

Answer 1

To check if it is possible to factorize a square trinomial you have to calculate the determinant:

Here we have:

#Delta=17^2-4*9*85=289-3060==-2771#

The discriminant is negative, so the trinomial has no roots (i.e. it cannot be factorized)

Yes, it is possible to factor the quadratic equation y = 9x^2 - 17x - 85. The factors are:

y = (3x + 5)(3x - 17)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
