Answer:
The best choice is to use a calculator (the button is ), but if that is not an option here are a few tips.
If a perfect square ends with a 1, then the last digit of its square root has to be either 1 or 9.
If a perfect square ends with a 4, then the last digit of its square root has to be either 2 or 8.
If a perfect square ends with a 5, then the last digit of its square root is definitely 5.
If a perfect square ends with a 6, then the last digit of its square root has to be either 4 or 6.
If a perfect square ends with a 9, then the last digit of its square root has to be either 3 or 7.
I took a look and all of them seem to be perfect squares so hopefully this helps!

Answer:
C.
Step-by-step explanation:
The zeros of a polynomial are the x-intercepts of the function. To find them, we factor the polynomial and set each factor equal to 0.
This polynomial is already factored so set each to 0 and solve for x.
This means x=-2, 5. Each zero or root has a multiplicity - the number of times the factor occurs. This is also known as the exponent of the factor expression.
(x+5) occurs once since it has exponent 1.
occurs twoce since it has exponent 2.
x=5 mult. 1, x=-2 mult. 2
