Do you know method of completing the whole square?

onyx flower
#

Um I'm kind of dumb mb

#

Um I don't think so

velvet tide
#

So basically you need to split the middle term in half

onyx flower
#

Oh 4

velvet tide
#

And then sqaure it

onyx flower
#

16

velvet tide
#

That number then you add and subtract

onyx flower
#

Um so a would be 4

#

??

velvet tide
#

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?

onyx flower
#

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

velvet tide
#

Let me show you the working for another example and you can solve this sum after?

onyx flower
#

That is all I get up to

#

Um ok

velvet tide
#

Wait

#

Did you understand this much?

onyx flower
#

Yes

#

16 minus 11

#

Is 5

#

Negative 5

velvet tide
#

Yup

onyx flower
#

So mine is

velvet tide
#

a is 4 and b is -5

#

Also one thing to note

molten bluff
#

(x+4)^2 - 5

velvet tide
#

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

onyx flower
#

Oh

velvet tide
#

Anything else?

onyx flower
#

Um I got 2 things but if dogedepressed does one of the things it's just 1

velvet tide
#

?

onyx flower
#

So I use same exact

#

Steps right

velvet tide
#

Yup

onyx flower
#

5

#

Minus 5

#

I ment

#

Minus 25

velvet tide
#

25

#

Yup

onyx flower
#

Then Minus 9 Minus 25

velvet tide
#

Correct

onyx flower
#

Minus 34

#

So it's x Minus 5

#

Is a

#

And b is Minus 34

velvet tide
#

Exactly

#

a = -5, b =-34
