Step-by-step explanation:
I'll do 2.
Alright,Alex let say we have factored a quadratic into two binomial, for example

If we set both of those equal to zero

We can used the zero product property in this case to find the roots of the quadratic equation.
This means that

This means we set each binomal equal to zero to find it root.






So our roots are negative 3/5 and negative 2/3 using zero product property

Answer:
24 miles.
Step-by-step explanation:
Jackie traveled four times as many miles by bus as by foot. This means that the number of miles travelled by bus is 4 units, and the number of miles travelled by foot is 1 unit.
Jackie traveled three times as many miles by train as by bus. We know that the number of miles travelled by bus is 4 units, so the number of miles travelled by train is
units.
Total number of units: 

Divide 17:

The number of miles travelled by train is 12 units:

She travelled 24 miles by train.
