What multiplies into 48 that adds up to -32? (Trying to do factoring for the problem: 4x² - 32x + 48)

Parth (parthkohli):

Why don't you first factor out the 4?

Parth (parthkohli):

\[\rm 4(x^2 - 8x + 12)\]

OpenStudy (anonymous):

Oh didn't think of that!

OpenStudy (anonymous):

Wait, what about this: 3x² - 17x - 6 ? You can't really factor out anything.

OpenStudy (anonymous):

What would multiply into -6 that could add to -17?

OpenStudy (anonymous):

Impossible!

Parth (parthkohli):

No. What could multiply into -18 that adds to -17? -18 and 1.

OpenStudy (anonymous):

Oh I see. Thanks
