In order to factor a polynomial, you have to find its roots

So that you can factor it as

So, in this case, we're looking for the solutions of

So, the polynomial can be written as

Answer:
7/100
Step-by-step explanation:
We want to write .07 as a fraction
7/100 were a = 7 and b = 100
Only A would. None of the others would work
Answer is 90 miles in 2 hours
Step by step
I like the cross multiply method for this. See attached picture with example.
We know she drove 30 miles / 40 minutes
We want to know “x” miles / 120 minutes ( equivalent of 2 hr)
Put into your equation
30/40 = x / 120
40x = 3600
X = 90 miles in 2 hours
