### Transcript

game of factoring begins with a round of identify the

g c f or greatest common factor quick hit that

buzzer already three c so let's pull out three c

right away and we get three seat times foresee squared

minus nine Ok interesting So now we've got a four

c squared minus nine Note that four and nine there

are perfect squares We'll only three commonly used words in

the english language Have a double u that's a u

u not a w This expression has some doubles too

in the form of identical factors for c squared here

factors toe to see times to see and nine equals

three three squared Well when two perfect squares they're subtracted

from one another The expression is called a shockingly difference

of two squares That's what it's called sexually a thing

The general formula for factoring a difference of two squares

is a squared minus B squared equals a plus b

a minus b this format right Here so a stands

for the factors of foresee squared which are to see

and b equals three right Use the general form to

a factor The expression here So we've got three c

times quantity to see plus three and then to see

ministry just like that The fact is that we factored

this expression into three c times equality thing Alright let's 00:01:34.553 --> [endTime] be we're done
