I won't solve three problems in one post, so I'll just give you three hints. 1. Substitute each of the answer values given and do the arithmetic. The answer that gives the smallest absolute value result is the correct answer. 2. Whenever the 
and 
coefficients have opposite signs, two real and distinct roots are guaranteed. 3. In order to have any real roots where the 
and coefficients have the same sign, the value 
must be less than or equal to the value 
.
