Answer:
the second one.... ( 8,9 )
Step-by-step explanation:
the zero-product system is rlly easy to use....
it basically means to take each term and equal it to zero....
so for your equation it is....
( x - 9 ) ( x - 8 ) = 0
so you would write it as....
( x - 9 ) = 0
and
( x - 8 ) = 0
and then you solve them like this...
( x - 9 ) = 0
add 9 to both sides to get the variable by itself...
x= 9
( x - 8 ) = 0
add 8 to both sides to get the variable by itself....
x = 8
