Answer:

hope this answer helpful for you.

Answer 2

Answer:

hope that u understood

z^2+4z-12

Step-by-step explanation:

first we have to find the factors of this eq. I.e 1×-12=-12

|

6.× -2

then . use the 6 and -2

z^2+6z-2z-12=0

z(z+6)-2(z+6)=0

(z-2)(z+6)=0

z=2. z=-6

factors are 2 and -6
