It looks as if the numerator and denominator need to be factored. Numerator: 4x^2 -32x + 48 contains a monomial factor of 4. 4x^2 -32x + 48 = 4 ( x^2 - 8x + ?) @lowcard2

12?

Directrix (directrix):

Yes. 4x^2 -32x + 48 = 4 ( x^2 - 8x + 12) = (x - ?)* (x - ?)

@lowcard2 ^^^^

2 and 6?

OpenStudy (anonymous):

1,-6?

Directrix (directrix):

Yes. Numerator: 4x^2 -32x + 48 = 4 ( x^2 - 8x + 12) = 4(x - 6)* (x - 2) Denominator: 3x^2 - 17x - 6 = ( 3x + ? )*(x - ? ) @lowcard2

Directrix (directrix):

4*(x - 6)* (x - 2) ------------- = @lowcard2 Divide out common factors. ( 3x + 1 )*(x - 6)

@lowcard2 Do you see what has to be the correct option?
