Do you know method of completing the whole square?
So basically you need to split the middle term in half
Oh 4
And then sqaure it
16
That number then you add and subtract
No in the sense x2 + 8x + 11 + 16 -16
Should i show you the entire working or do you want to go about it yrself?
Um to be honest I don't even know how to properly do this
I'm trying to figure out what to do
So u divide 8 by 2
And u get 4
And that's is square
16
Let me show you the working for another example and you can solve this sum after?
Thts correct, but it actually if you think about it logically, if you have
Wait
Did you understand this much?
Yes
Correction at the top its 2xy
Try the same with your question
Yup
So mine is
(x+4)^2 - 5
Even if the middle term is negative, you will still consider the positve value only, since square of numbers is +ve. Only in the answer itll be (x-a)^2
Oh
Anything else?
Um I got 2 things but if dogedepressed does one of the things it's just 1
?
Yup
Then Minus 9 Minus 25
Correct
Wow thank u
Just one last part of my hw
And sum1 in the server is trying to help me
And it's probably the hardest of all
No problem haha. Make sure to remember this since it may come in calculus and all
This is pretty easy tho
Nevertheless, glad you understood
Do remember to mark the channel as solved!
Um how do I do that ?
.solved
