can someone teach me a simple way, VERY VERY SIMPLE WAY to factor trinomials?

OpenStudy (anonymous):

Quadratic trinomials?

OpenStudy (anonymous):

well im not sure just a trinomial like 9y^2-12yz-4z^2, i know how to solve them by just multiplying different numbers together, but what is the trinomials become greater numbers like 30 and 40?

OpenStudy (anonymous):

actually, could you explain how to factor this problem?: 9a^2+4bc-4c^2-b^2

OpenStudy (anonymous):

This one has a specific way

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

its tough..but you can make out that it is of the form 9a^2 - (b^2 -4bc+4c^2) cant you?

OpenStudy (anonymous):

o yes! thanks!!!!!!

OpenStudy (anonymous):

now the second part..look at it...if you can make it a perfect square..you can use the formula for differnce of squares cant u?

OpenStudy (anonymous):

x^2-y^2=(x+y)(x-y)?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

can you make the second term perfect square?

OpenStudy (anonymous):

i think so

OpenStudy (anonymous):

it is (b-2c)^2

OpenStudy (anonymous):

can u listen to me? instead of being impatient

OpenStudy (anonymous):

i am

OpenStudy (anonymous):

so the second term is (b-2c)^2 so uve got a^2 - (b-2c)^2 can u factor that out?

OpenStudy (anonymous):

it would be (a-b-2c)(a-b+2c)

OpenStudy (anonymous):

a+b-2c

OpenStudy (anonymous):

how?

OpenStudy (anonymous):

the first trm is a+b-2c

OpenStudy (anonymous):

ok and?

OpenStudy (anonymous):

second is fine

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

theres no way to it...just practice
