Answer:The roots of any quadratic equation is given by: x = [-b +/- sqrt(-b^2 - 4ac)]/2a. Write down the quadratic in the form of ax^2 + bx + c = 0. If the equation is in the form y = ax^2 + bx +c, simply replace the y with 0. This is done because the roots of the equation are the values where the y axis is equal to 0.

Step-by-step explanation:
20% as a decimal is 0.2
For each year get the amount of increase by multiplying the number of rabbits by 0.2
Rabbits in 2013:
25 x 0.2 = 5
25 + 5 = 30 rabbits
Rabbits in 2014:
30 x 0.2 = 6
30 + 6 = 36 rabbits
Rabbits in 2015:
36 x 0.2 = 7.2
36 + 7.2 = 43.2
Rabbits in 2016:
43.2 x 0.2 = 8.64
43.2 + 8.64 = 51.84
Rabbits in 2017:
51.84 x 0.2 = 10.368
51.84 + 10.368 = 62.208
= 62 rabbits
