Answer:
-4 and 2
Step-by-step explanation:
factor: (x+4)(x-2)=0
x+4=0,. x-2=0
x=-4,. x=2
( x + 4 )( x - 2 ) = 0
x² - 2x + 4x - 8 = 0
x² + 2x - 8 = 0
( x + 4 )
x + 4 = 0
x = - 4
(-4)² + 2(-4) - 8 = 0
16 - 8 - 8 = 0
8 - 8 = 0
0 = 0 ✔︎
( x - 2)
x - 2 = 0
x = 2
(2)² + 2(2) - 8 = 0
4 + 4 - 8 = 0
The values of X are, x = - 4 and x = 2 po
sana tama at makatulong po..
