Answer:


x=\pm2i\sqrt{(2)/(3)}

Explanation:

we have


3x^(2)-6=-14

Solve for x

Adds 6 both sides


3x^(2)-6+6=-14+6


3x^(2)=-8

Divide by 3 both sides


x^(2) =-(8)/(3)

square root both sides


x=\pm\sqrt{-(8)/(3)}

Remember that


i=√(-1)

so


x=\pm i\sqrt{(8)/(3)}

simplify


x=\pm2i\sqrt{(2)/(3)}
