Question

Help please

Answer 1

Yes?

Answer 2

@mww

Answer 3

16

Answer 4

if u add and subtract 64 u will get the answer

Answer 5

this is very easy, a trick question in fact. Difference of two squares involves two numbers - that being one square number/pronumeral minus another square number
So you require only two terms.

what would the ? be to ensure this condition is met.

Answer 6

@avi13 it is not asking to complete the square or make into a perfect square, just to make a difference of two squares

Answer 7

why cant it be 0?

Answer 8

\[(x+6)(x-6)=x^2-36?\]

Answer 9

6?

Answer 10

@mww i didnt make it perfect square actually.i made it difference of two square.. (x+8)^2-10^2

Answer 11

I had 0 in mind

Answer 12

i used pythagoras triples (6.8,10) in this

Answer 13

Can somebody just help me :(

Answer 14

I believe the goal of this question is to show that different factoring techniques apply depending on number of terms given

Answer 15

\[x^2-6^2\]
this seems to fit the bill too right?

Answer 16

yeah so a question can have multiple answer as well

Answer 17

This question will only have one correct answer fyi

Answer 18

@avi13 That is true...

Answer 19

@zarkam21 but we just came up with two correct answers...

Answer 20

well it has to be 0. Simply said difference of TWO squares generally involves two terms. the easiest response

Answer 21

yeah i think so

Answer 22

for instance if they asked me to factorise a trinomial I do not use difference of two squares immediately. it is a secondary choice

Answer 23

it need not to be that tricky.....that i thought it is

Answer 24

6?

Answer 25

no 0

Answer 26

@mww is this correct? Just a second opinion

Answer 27

x^2+0*x-36

Answer 28

0 is what will make the question have TWO terms for which difference of two squares can be applied directly. IT's much harder to use difference of squares for more than 2 terms.

Answer 29

Hi,
This is the property
When we have
X^2 +?x. -36
You need to make 2 set of parentheses and take the perfect sqrt of each the 1st and last term
Such that
(x + 6) (x-6)
We took the sqrt of x^2 and 36
Now distribute to see the value of the 2nd term
X^2 -6x + 6x -36
Thus simplify
X^2 +0x -36

Answer 30

So 0?

Answer 31

@mww so is it 0 or no

Answer 32

Those other people came in and confused me

Answer 33

@steve816

Answer 34

yes zero obviously
