Best ResponseYou've already chosen the best response.2Find the discriminant. \[\text{ If you have } ax^2+bx+c=0 \text{ , then the discriminant is equal to } D= b^24ac .\] If D=0, then one real solution (with multiplicity 2) If D=negative real number, then no real solutions. If D=positive real number, then 2 real solutions.

Best ResponseYou've already chosen the best response.2I don't know what dismals mean but yes D would be a positive real number which implies 2 real solutions. You have a=6,b=7,c=1 You put these in the formula I gave above for the discriminant.

Best ResponseYou've already chosen the best response.1Tip: when "a" and "c" are of opposite signs, you will always have real solutions.
