What type of equation is 2x^2 + 3 = -1?

Linear
Quadratic
Exponential
Radical

The correct answer is: Quadratic

2x^2 + 3 = -1 is a quadratic equation because it has a degree of 2 and can be written in the form ax^2 + bx + c = 0, where a, b, and c are constants. Option A Linear equations have a degree of 1 and can be written in the form mx + b = 0. Option C: Exponential equations have a variable in the exponent, such as 2^x. Option D: Radical equations involve square roots or other root operations, such as √x or ∛x. These types of equations do not have an x^2 term. Therefore, the correct answer is B: Quadratic.
