There are an infinite number of different quadratic equations. The quadratic formula is a single formula that can be used to find the pair of solutions to every quadratic equation.

An expression has no equal sign whereas an equation does have an equal sign

An equation has an equal = sign whereas an expression does not.

radical equations have sq roots, cube roots etc. Quadratic equations have x2.

An equation is a ploblem with no answer and an expression is a problem with an answer so you'll get different answers with an equation and an expression.

The difference between these two is that an expression only contains variables, numbers, and mathematical symbols, and an equation contains two expression with an equal sign that separate them. For example, while an expression is "2x-1", an equation is "2x-1 = 5x."

Simply put, an expression does not need an equal sign, while an equation does. Equation: x+y=z Expression: x+y

A linear equation has the form of mx + b, while a quadratic equation's form is ax2+bx+c. Also, a linear equation's graph forms a line, while a quadratic equation's graph forms a parabola.

There is no quadratic equation that is 'linear'. There are linear equations and quadratic equations. Linear equations are equations in which the degree of the variable is 1, and quadratic equations are those equations in which the degree of the variable is 2.

similarity: both involve arithmetic operations and/or functions difference: an equation either produces an answer or shows how two expressions are equal, an expression does not produce an answer and is usually a portion of an equation or a larger expression
