Whenever the coefficient of x<sup>2</sup> is something other than 1, there can be more than one possibility. In this case, it could either be:

. . . . (2x + ?)(2x + ?)

or:

. . . . (4x + ?)(x + ?)

Definitely try both possibilities when you go to factor this polynomial.

G

b<sup>2</sup> - 4ac

= 1<sup>2</sup> - 4 * 4 * (-6)

= 1 + 96

= 97

which is not a perfect square. You could use the quadratic formula to factor this, or you might just say it's "prime".
