∙ 12y agoAnswer 1 == In an open sentence (an equation or inequality with a variable in it), when a number replacing the variable makes the sentence true, then it is a solution.
An equation can often be re-written so that the subject of the equation is changed. This makes it nonsense to define either variable as independent.
Solution

insert the answer in the equation, replacing the variable, and see if it still makes sense.
An equation or an inequality that contains at least one variable is called an open sentence. ... When you substitute a number for the variable in an open sentence, the resulting statement is either true or false. If the statement is true, the number is a solution to the equation or inequality.

The Quadratic Eq;n , when plotted on gaph paper, will reveal a parabola. This patrabola can intersect the x-axis in two places, just touch the x-axis or miss it altogether. The roots of a quadratic eq;n are the point(s) were the parabola intersects the x-axis. If is intersects at two points, then there are two roots. If it just touches the x-axis, then there is one root only. If it does not touch the x-axis, then the eq'n remains unresolved.
It's the value that when substituted in for the variable, makes the equation true. Ex: x + 1 = 3 The value 2, when substituted for the variable x, makes the equation true.
That's the "solution" of the equation.

In algebra, variables are represented by letters such as x. A variable could be any number. That number is the "value" of the variable. In an expression, you can choose a number to put in for x, and simplify to get a number which is the value of the expression. In an equation, you can solve for the value of x, which will be the value of x which makes the equation true.
Such a value is said to be a solution, or a root, of the equation.
