hello, video was great but at the and when you had equation K^2-3k+9=0 here we wont have real roots due to D=9-4*9=-27 so you can not put negative number under square root otherwise it would be 3+-3sqrt{3}i then it would be 6 roots but 4 of them are real and 2 are imagenery
Great video Mam! Always lots of learning in your lessons. Many thanks.
U are welcome
Doeas this need to go through all of these steps.
Yes
