x2 + x - 2 is an expression, not an equation. An expression cannot be solved. There is no way of knowing if the expression is equal to 0 or 10 or -3/7 etc and so it cannot be solved.

x2 + x - 2 is a polynomial of the second degree.

Every polynomial defines a function, often called P. Any value of x for which P(x) = 0 is a root of the equation and a zero of the function. Moreover, for any value of x you can find a corresponding value of P(x), often called y. Then, any pair (x, y) that you've found is called a solution of y = x2 + 2x - 1.
