Final answer:

To solve the equation -3x²+2=0 using substitution, let x² equal to -2 and solve for x.


Step-by-step explanation:

To solve the equation -3x²+2=0 using substitution, we need to let a variable equal to one term of the equation and substitute it into the other term. Let's solve for x². Start by subtracting 2 from both sides: -3x² = -2. Divide both sides by -3: x² = 2/3. Finally, take the square root of both sides to solve for x: x = ±√(2/3).
