Solve the quadratic equation:
2x(squared)+6x+12=0
I know you have to find two numbers that =24 (2 times 12) and have a sum of 6. But I can't think of any! Can someone please help?
Use the quadratic.
And this problem has no real answers, they are imaginary.
Oh, the quadratic formula? Lol, why didn't I think of that?! Sorry, but thanks!!!
