IT'S FRIDAY, FRIDAY GETTIN' PRECAL DONE ON FRIDAY !

TOPIC: SOLVING ABSOLUTE VALUE EQUATIONS . (continuation)

hey guys,

it's christian narciso, signing in on his spare to scribe about what we did in class yesterday .

im just going to do a quick scribe since this morning since no one decided to do one for yesterday's class and since i had work last night i wasn't able to do it myself, so i'll do it now ha..

so, yesterday in class all we did was solve for the absolute value of |x| in an equation that was given . we would change that absolute value of |x| into brackets so it would look like this (x) . then we would solve for x like we would originally do. it's pretty easy. for example, given this equation:

we would then change the absolute value of x into brackets .
so it would now look like this:
then we would solve x, which in this case is already solved . so:


this was just the first step, the second step is to take the same equation again and place a negative in front of the original equation then solve for x again. once we are done that step we place our x values into the absolute value of x (basically the originally equation), and equate it so both sides equal the same value .

so from the previous equation above we would place |x| as our value of x which is 3 and it should equate to the same value on both sides, so the final product should looks like this:

hope this helped anyone that was having trouble with solving for absolute value of x !
i'm not too great with precal, but im understanding it. very slowly though .. HAHA

signing off,

i mean, christian narciso !
