Yeah Whoa Okay CT mash bumpers Another weird quadratic equation
- 00:07
for you here We got this thing given the following
- 00:09
equation where a B and C are constants with the
- 00:12
value of B All right so we're trying to find
- 00:17
this term here in all this mess Well the left

- 00:20
side of the equation has two identical parent testicles Do
- 00:22
we smell some factoring in our future We love the
- 00:26
smell of factoring in the morning All right So we're
- 00:30
gonna slow down here and think about our end goal
- 00:32
We want to see what be equal So we need
- 00:35
to multiply out everything on the left side and see
- 00:37
what coefficient is glued to the ex term Sure we
- 00:40
could factor then distribute then combined like terms But like
- 00:43
why let's cut out the middleman here And be sure
- 00:46
you used this safe the scissors and just jump right
- 00:48
to the distributing You gotta remember what we're solving here
- 00:51
And time matters These tests are times right So let's
- 00:54
just distribute everything out here we've got here is primary
- 00:58
equations We got ten x squared We must buy that
- 01:00
five accident to X and then we've got forty x
- 01:04
there and then six x there And it was three
- 01:08
times twenty four equals that X word Bxc OK then
- 01:11
we kind of combined some terms here We got ten
- 01:13
x squared plus forty six Acts plus 24 so and
- 01:18
this is all great but the only term we really
- 01:20
care about is the coefficient of X right there which
- 01:23
is B It's forty six That's it We're done answers 00:01:26.82 --> [endTime] Forty six No
