factor a quadratic expression by thinking of factors of the
- 00:23
constant term that add up to the coefficient of the
- 00:27
ex term Well in this case the constant term is
- 00:30
one indicated in bold here that thing right there and
- 00:33
the coefficient of the ex term is negative to this
- 00:36
thing So we're looking for two factors of one that
- 00:40
add to negative too Well the answer choices only gives
- 00:43
singers and the possible factors have won So it's safe
- 00:46
to say we have a living A number of possibilities
- 00:48
Well there are only two pairs of factors of positive
- 00:51
One that's one and one and negative one and negative
- 00:55
one Well the southern negative one and everyone sang of
- 00:56
two so we could factor the given expression as x
- 00:59
minus one times x minus one or cleverly known as

x minus one squared So that's it Quadratic work They
