kat is right

kat is always right lol

Okay first you have to split this into 2 equation equation terms..
So we know we have break w^4 into 2 w^2 since they will still equal w^4
Then look into the sign of the eqaution given..which is w^4 - 144
Since it is MINUS we know that we have to have a negative AND positive symbol for each equation..
So it would be
(w^2 + ___) (w^2 - ___)
Now the square of 12 is equal to 144..So we know that 12 would substiute it in the blanks..
So
(w^2 + 12) (w^2 - 12)
Adn there is your answer

Hehe thanks =D

good work katrina
\[(w^2)^2-(12)^2\]
\[(w^2+12)(w^2-12)\]
OpenStudy (anonymous):
w^4 can also be written as (w^2)^2
and also 144 can be written as (12^2)
according to the property ( a^2-b^2 ) = (a+b)(a-b)
OpenStudy (anonymous):
hence the answer is ::::::::::::
\[(w^2+12)(w^2-12)\]
