Question

Which of the following is the solution set of x² + 8x + 12 = 0?

{2, 6}
{-2, -6}
{}

Answer 1

{-2,-6} because you can try out each solution to check if the equation works and {-2,-6} works, if that makes any sense. Hope I helped!(:

Answer 2

Solve 2x² - 11x + 5 = 0.

{1/2, 5}
{5/2,1}
{}
