Which polynomial is a difference of two squares?
x2 − 16
x2 16
x2 − 8
x2 8

Option A is correct.

Step-by-step explanation:

We have to find: Polynomial which is difference of two square.

Option A).

x² - 16

It can be written as x

= x² - 4²    (since 16 is square of 4)

So, this is correct Option.

Option B).

x² / 16

It can be written as x

= x² / 4²    (since 16 is square of 4)

So, this is not correct Option as there is division between them.

Option C).

x² -  8

So, this is not correct Option as 8 is not square of any real number.

Option D).

x² / 8

So, this is not correct Option as there is division operation between them.

Therefore, Option A is correct.

step-by-step explanation:

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
