Answer 5

A difference of two squares is a binomial (two terms, one with an x variable and one regular ol' coefficient) expression. It is finding the difference of one squared number and another squared number

ax^2 - b
a is a square
b is a square

In order find if it's a difference of two squares, find out if A and B are squares, by finding their square roots.

Answer 11

my phones dead i cant use siri my charger broke

Answer 12

why do you need siri?

Answer 13

Okay, we'll take this step by step.

A square number is a number that can be divided by one number and also equal that number.

\[a \times a = a^2\]

\[a^2 = squared number\]

Answer 14

So, 14 cannot be a square. Nothing multiplied by itself equals 14. Meaning, this one can not be a difference of two squares, because there's only one square (81).

Don't get upset, it's okay :) You can always ask for help on whatever you're confused about

Answer 15

14 isnt a choice tho

The 14 comes from the 14x^2
Sorry, I should have explained that :)
