Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.

Solve by factoring. Solve by taking the square root of both sides.
when you find the value, you SOLVED the equation. you CHECK the equation when you substitute the value in the variables place and check that the equation is true.
Not sure what you mean by "zero element". If an expression is equal to zero, and you can factor it, then at least one of the factors must be zero; this is often useful to solve an equation.
The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is 0.
The quadratic formula cannot be used to solve an equation if the coefficient of the equation x square term is what?
It depends on the equation that is being solved.
The quadratic formula can be used to solve an equation only if the highest degree in the equation is 2.
It is used to solve quadratic equations that cannot be factored. Usually you would factor a quadratic equation, identify the critical values and solve, but when you cannot factor you utilize the quadratic equation.
2.
g= Eight Fifteenths
Trial and Error in science, or else you can use a (chemical) equation to solve and check.
Two.

None. Properties of inequalities are not that relevant when solving equalities.
you don't answer an equation, you solve an equation
