Algebraic expressions can't be solved because they are not equations but they can be simplified.
A quadratic equation can be solved by completing the square which gives more information about the properties of the parabola than with the quadratic equation formula.
If you mean 3x2+4x-2 = 0 then it can be solved by means of the quadratic equation formulla
No, you can only simplify an expression. To solve for a variable, it must be in an equation.
No, but they are symmetric with respect to a line parallel to the y-axis - which could be the y-axis itself.

It is a quadratic expression in x, which is equivalent to 3*(x+1)*(x+5). Since it is not an equation it cannot be solved.
The discriminant
The quadratic formula is used to solve the quadratic equation. Many equations in which the variable is squared can be written as a quadratic equation, and then solved with the quadratic formula.
It is a quadratic expression in x and y. Since it is not an equation it cannot be solved or represent any shape in the 2-dimensional plane.
a2b2 - 2ab - 25 is a quadratic expression in the variables ab. There is no equation or inequality in the question so there is nothing that can be solved. Because of the nature of the expression a and b cannot be separated in any meaningful way.
It is a quadratic expression in one variable, x (assuming that x and X are the same). Since it is not an equation, it cannot be solved. Also, it has no real factors.
A quadratic equation normally has 2 solutions and can be solved by using the quadratic equation formula.
This is a quadratic expression in x. It cannot be solved because it is an expression: there is no equation to solve. Furthermore, the discriminant for the quadratic = (-10)2 - 4*3*(-5) = 100+60 = 160 which is not a square number. There are, therefore no rational factors. While it would be possible to give irrational factors, factorising a quadratic into linear terms containing irrational numbers is rarely useful.
No. An expression cannot be solved.
This equation (where the above expression equals 0) has imaginary roots and so will need to be solved using the quadratic formula and the use of the imaginary number i.
Sometimes it can be simplified
