Question 708103
This is an important rule to know:
If a is a real number, then a*0=0.


This is another important thing to know:
If a and b are real number, and if a*b=0,
Then either a=0, or b=0, or both a and b are zero.


Now, what can you do with those two binomial factors in your given equation?

Either [_____________] or [______________].




Can 2x+7 be zero?  How?
Can 3x-1 be zero?  How?
