is defined to be why Zero All right The question

00:19

here which of the following equivalent equations best reveals the

00:23

possible locations on the roller coaster where boarding or AH

00:27

disembarking or vomiting takes place after the ride is finished

00:35

Like Southwest Airlines You know you got the A and

00:37

the B and the losers and see weigh them All

00:40

right What are we looking for here Nothing Absolutely nothing

00:43

Say it again before you let out a whoop and

00:45

move onto the next problem here Us out The nothing

00:48

we need to find here are the zeros i e

00:51

The ex intercepts because that's the height at which passengers

00:54

board right You're going to board on ground level and

00:56

then you take off So we have a quadratic tried

01:00

and true method going forward here Factor it If we

01:02

can and set the whole thing equal to zero we'll

01:05

just skip that last step because well we want the

01:07

equation with why intact That makes the X intercepts stand

01:12

out like you know my grandma Metallica Okay well there's

01:17

equation and then they were going to factor it out

01:19

So we're gonna pull out a negative x here and

01:21

next there and then a three Tempting to fifteen actually

01:23

See the naked forty five to the equation has a

01:26

clean factored form available here And it's why equals negative

01:31

X plus three and Acts minus 15 and answers a 00:01:35.67 --> [endTime] no roller coaster there That was a easy ride
