We planted them all the graph of y equals x
- 00:13
squared minus two x plus six is shown beloved what's
- 00:17
the value of a and here's the bench lands Okay

let's take a quick inventory way Have a problem We
- 00:24
have a graph and we have our brain Hopefully that's
- 00:26
enough The equation of the parabola is given its why
- 00:29
equals x squared minus two x plus six and we're
- 00:32
being asked to find the value of a right No
- 00:36
problems There are a few points this parable of passes
- 00:39
through i look to this graph Negative six zero hero
- 00:43
thing two zero we can plug in any of them
- 00:46
But what fans of small numbers around here so let's
- 00:49
use to zero the equation will become zero equals a
- 00:53
times two squared minus two times to plus six We
- 00:57
could clean that puppy up a bit but two squared
- 01:00
is four and two temps two is also four so
- 01:03
we can rewrite as zero equals for a minus four
- 01:06
plus six and of course the minus foreign plus six
- 01:09
Or really just positive too So we're left with zero
- 01:12
equals four a plus to subtract two from both sides
- 01:15
to get negative Two equals for a then divide Both
- 01:18
sides fight for to get negative a half people's a
- 01:20
and it looks like our answer is c nice work 00:01:23.092 --> [endTime] framed on your end
