The way you put it is confusing. I'll answer but the way you put it was confusing to me.
Answer:
roots: -4 and 7
Step-by-step explanation:
where the graph crosses the x axis is where the roots are located
You multiply it with the same number you use for the denominator.
in this case 3/4 and 7/10
you find the LCM of the denominator is 20
so for 4 to become 20 you multiply by 5 then for the numerator 3 also multiply by 5, so you get 15/20
its the same also with 7/10, you multiply both the numerator and the denominator by 2 and get 14/20
hope it help... :)
