Z^2- 2z-8 pls solve fast |
|
Answer» (z-2)(z-4)Step-by-step explanation:z^2-2z-8 We will use mid TERM break as 8 is not a PERFECT square so identity will not work . find the factors of 8 1×8=82×4=8 so factor 2 and 4 will be CHOSEN ... Why ??? because when you add 2 and 4 you get 6 and when you subtract 2 and 4 you get 2 and 2 is the number in the between ..and z = a here a = 1 so the ANSWER is (z-2)(z-4)GIVE ME BRILLIANT |
