factor the trinomial 3x^2+14x-5

OpenStudy (anonymous):

multiply the 3 and 5, get the factors of 15, now which two numbers will give you 14

OpenStudy (anonymous):

the sum or product

OpenStudy (anonymous):

the factors are 1 3 5 15

OpenStudy (anonymous):

ya so youll use 15 and 1

OpenStudy (anonymous):

ok so it will look something like this x^2(x-15)(x-1)

OpenStudy (anonymous):

so then set up the trinomial as 3x^2+15x-1x-5

OpenStudy (anonymous):

then youll perform factoring by grouping

OpenStudy (anonymous):

ok and what does that step look like please

OpenStudy (anonymous):

(3x^2+15x)(-x-5)

OpenStudy (anonymous):

then youll get 3x(x+5)-1(x+5)

OpenStudy (anonymous):

since the x+5 matches your answer will be (3x^2-1)(x+5)

OpenStudy (anonymous):

(x+5)(3x-1)

OpenStudy (anonymous):

ya correct my bad

OpenStudy (anonymous):

o well two more shots

OpenStudy (anonymous):

so you got this now?

OpenStudy (anonymous):

still wokring on it slowly maybe
