difference of two squares

maiden python
#

what does that mean

jolly dust
#

$a^2-b^2=\left(a-b\right)\left(a+b\right)$

maiden python
#

36p^2- (-1) ?

#

OR WOULD IT BE 5 INSTEAD OF 36

#

cuz 6 x 6

jolly dust
#

yes

maiden python
#

and remove squared?

jolly dust
#

6p x 6p = 36 p squared

#

and -1 x -1 = 1

maiden python
#

okk thank you

jolly dust
#

,w factorise 36p^2 -1

#

how do i do it if it s cubed

jolly dust
#

$a^3-b^3=\left(a-b\right)\left(a^2+ab+b^2\right)$\\$\text{or }a^3+b^3=\left(a-b\right)\left(a^2-ab-b^2\right)$

maiden python
#

damn alot of formulas

jolly dust
#

once you use them lots and get a good understanding of where they come from it’s hard to forget them

maiden python
#

which one is easier

#

the top one of bottom

#

or i need both

jolly dust
#

you have the negative sign so use the top

maiden python
#

kk

jolly dust
#

they’re both the same thing just with different signs

maiden python
#

oh ok\

#

i use gcf?

#

so 5 x 25

jolly dust
#

yes

#

also cube root of 125 is 5

#

5 x 5 x 5 = 125

maiden python
#

oh ok

jolly dust
#

yeah

jolly dust
maiden python
#

how would i do tht

jolly dust
#

never mind there is no factor my apologies

#

it is in simplest form

#

,w factorise f^3-125

harsh estuaryBOT
maiden python
#

ok thanks

#

wait its 25 at the nend

#

or 5

#

o nvm i put 5 squared

#

25 and 5 squared both accpetable right
