facial expressions caused by this outbreak expression have been known

to include happy anxious and surprised You know like that

before this initial reaction fades to discuss do a little

substitution to remove the variables Substitute The values are equal

six and that's equals negative to into the expression right

here Parentheses Prevent signe errors and subsequent expressions of anguish

like that Constipated Okay so we rewrite this thing as

just with the big brackets there one minus and then

parentheses negative too And then squared And then over the

sixteen So put on an expression of determination The one

that looks like constipation too The one with furrowed eyebrows

Yeah that's better Thanks to the order of operations Parentheses

are the place to start Well in this expression there

are princes in princes in brackets So we start with

the innermost set and then work outwards So that gets

us teo Well one minus negative two squared over six

and we're going to do the quantity one plus two

because minus a negative is that so that's just three

squared which is nine and we're over six there So

nine over six in the parentheses Well that then gets

multiplied by three there and there are a couple of

ways to approach the final simplification But we'll cancel common

factors between the numerator and denominator first because we refer

to work with smaller numbers It's easier in the less

likely for ares So divide both three and six by

the common factor of three to simplify those values And

we got three tons quantity nine over six which is

really going to be three crossed out there and that

too And so it just gets you nine half that's

it The answer is c nine over to here's our 00:01:50.778 --> [endTime] expression of satisfaction over that one
