Answer:
-3,4
Step-by-step explanation:
(2x+6)(x-4) = 0
Using the Zero Factor Principle: If ab =0 then a=0 or b=0
2x+6=0 or X-4=0
solve 2x+6=0:
2x+6=0
Subtract 6 from both sides
2x+6-6 0-6
Simplify
2x = -6
Divide both sides by 2
2x/2 = -6/2
Simplify
X=-3
then x-4 =0
add 4 from to both sides
x=4
zeros : -3,4
(-3,0),(4,0)
