OpenStudy (anonymous):

@some_someone could you just tell me which method to use

OpenStudy (anonymous):

okaii try these steps: 20z^(2)+22z-12 Factor out the GCF of 2 from the expression 20z^(2). Factor out the GCF of 2 from the expression 22z. Factor out the GCF of 2 from the expression -12. Factor out the GCF of 2 from 20z^(2)+22z-12.

20z^2 + 22z - 12 = (2)(10z^2+11z-6)?
