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.

How do you solve x2 plus 3x4?
This is an expression and you do not solve an expression, but you can factor this one.X2 + 3X4X2(1 + 3X2)========
Solve the equation y' plus x2y equals x2?
(2x)ysquared
Solve x2 plus 10x plus 25?
(x+5)^2 and therefore x = -5
How do you solve x-1 plus x2-x plus x3-x2 plus x4-x3?
x4 - 1.We can not "solve" this as we have not been told the value of x. However, we can simplify this expression:We have an x and a minus x here which will cancel out. Likewise the x2 and x3 will cancel out with the -x2 and -x3 respectively. This therefore leaves us with just x4 - 1.
X2 plus 5x plus 6 how to solve?
x2+5x+6 = (x+2)(x+3) when factored because 2 and 3 are factors of 6
