Question

How many real solutions does 2x^2−4=−3x2 have?(1 point)

Answer 1

The equation is 2x^2 - 4 = -3x^2. Simplifying, we get 5x^2 = 4. To solve for x, we divide both sides of the equation by 5, which gives x^2 = 4/5. Taking the square root of both sides, we get x = ±√(4/5). Therefore, the equation has 2 real solutions.
