Question

for what value of K will the equation 3x^2=K-2x have real roots?

Answer 1

3x^2 + 2x - K = 0

you need to find an expression for the discriminant and put it > 0 and then find the values of K

are you familiar with the discriminant ( b^2 - 4ac ) ?

Answer 2

>=

Answer 3

yes it should be >=
