I need understand the concept of the difference between the equations. This question is from textbook Beginning Algebra
You can put this solution on YOUR website! Any equation in general is called an algebraic equation. But where as when we talk about an linear equation, its an equation in the form of y = f(x) = ax + b. That is here we observe that the power of x is one.
That is x is always raised to the first power in a linear equation.
As quoted by you as an example (2x + 8) we see that in the equation x has the power of one. so hence we can conclude that it is a linear equation.
Where as in the second equation ( ) we observe that the power of x is 2. hence its an algebraic equation called in general, but usually(in practice) called a quadratic equation.
