x^2 + 3x +7 = 0 doesn't factor neatly. Applying the quadratic equation, we find two imaginary solutions: (-3 plus or minus the square root of -19) divided by 2x = -1.5 + 2.179449471770337ix = -1.5 - 2.179449471770337iwhere i is the square root of negative 1

do you mean, x2 = n?? Take the square root.
x2+3i=0 so x2=-3i x=square root of (-3i)=square root (-3)square root (i) =i(square root(3)([1/(square root (2)](1+i) and i(square root(3)([-1/(square root (2)](1+i) You can multiply through by i if you want, but I left it since it shows you where the answer came from. Note: The square root of i is 1/square root 2(1+i) and -1/square root of 2 (1+i) to see this, try and square them!
It is an expression, in a variable x. Since it is not an equation, it cannot be solved.
The solution of the equation.
A root is the solution of the equation when one side (usually the Right Hand Side) is set equal to 0.To take very simple examples, x = 3 isthe solution of 2x = 6 orthe root of 2x - 6 = 0
root
It is the solution to the equation or a root of the equation.
Such a value is said to be a solution, or a root, of the equation.

Such a value is called a "solution" or "root" of an equation.
It is the solution; sometimes also called the root.
It is the solution or root of the equation.
A solution or root makes a true statement when substituted in an equation.
I assume you mean, in an equation. Such a number is called a "solution" or a "root" of the equation.
Such a value is called a "solution" or "root" of an equation.
