We know that: 3(x-1)^2-162=0
or (x-1)²= 162:3
and (x-1)²= 54
we take the square root of both sides
* x-1=√54= 3√6 or x=1+3√6
* x-1= -√54= -3√6 or x=1-3√6
This equation has 2 solutions

Adding integers (+6)+(+2)

noname [10]

Answer:

$6 + 2=8 \\so... +2 + +6 = +8\\$

Step-by-step explanation:

So the thing about adding of integers is that is both nos. are positive then you can simply add it and same with negative too.But with negative and positive we should subtract but that is for later.Luckily we have 2 positive integers so we do it like this:

+6 is the same as 6 and +2 is the same as 2 so we...

rule:add the numbers and add the sign.

$6 + 2=8\\so... +2 + +6 = +8$
