the answer is (-7-sqrt(57))/-4 and (-7+sqrt(57))/-4

Explanation:

keep in mind: quadratic formula: (-b+sqrt(b^2-4ac)/(2a))for this, you have to use the quadratic formula
-7sqrt((7)^2-4(-2)(1) divide it all by 2(-2) which is -4 now solve the equation in the sqrt which would give you -7sqrt(49+8) then you get -7sqrt(57) but you still have -4 and since it's sqrt, you ave negative and positive. that's how you get your answe
