radical equations have sq roots, cube roots etc. Quadratic equations have x2.

is this what you were looking for? there are many different types of quadratic formulas-- -b √ b^2 - 4ac = x (over) 2a
Technically,no. A radical equation has a radical (Square root) in it, and has two solutions because the square root can be positive or negative.
The term inside the square root symbol is called the radicand. There isn't a specific term for it based on its sign; whether it's positive or negative, it's still the radicand.I'm a little confused by your reference to the quadratic equation.If the radicand is negative, the root is an imaginary number, though that doesn't specifically have anything to do with the quadratic equation in particular.If the quantity b2 - 4ac is negative in the quadratic equation, the root of the quadratic equation is either complex or imaginary depending on whether or not b is zero.---------------------------Thank you to whoever answered this first; you saved me a bit of trouble explaining this to the asker :)However, in the quadractic equation, the number under the radical is called the discriminant. This determines the number of solutions of the quadratic. If the radicand is negative, this means that there are no real solutions to the equation.
The discriminant
the index in a radical equation appears above and left of the root symbol and tells you what kind of root the radicand is.
