Directrix (directrix):

The dominant term in the given expression 2x2 – 2x + 7 is 2x^2. Looking at the options, the last option begins with 2x^2. While that is not a guarantee that it is the correct option, let's simplify it.

Directrix (directrix):

5x^2 - 8x + 120 - 3x^2 + 10x + 13 looked promising but the 120 and the 13 do not add to the 7 of the given problem. We'll have to look at another option.

Directrix (directrix):

@maclover668 Simplify the second option and post what you get, okay?
