In this part we will explain the meaning of Quadratic expression and equation so as to make you bright understanding on next lesson: Before we continue, let’s check the meaning of expression. In mathematics we have something called term; a term is a single number or letter that expresses something. For example. 5, 2x, 1.9, When we join these terms with any operation symbols like +, - , ×, and ÷ we get mathematical expression. Now what is Quadratic deals with variable with highest power "2”. So in quadratic expression we define as the
x
The only thing that makes an expression to be an equation is an equal sign "=”; if we add an equal sign in any mathematical expression, we’ll change it to equation. For example: 2 + 4, this is an expression but if we add equal sign it will be an equation "2 + 4 = 6”. Even this quadratic expression x
So in quadratic equation we define as the
Quadratic Expressions: (1) x
Quadratic Equation: (1) x
The formula of quadratic is formed as:
^{2}, "b” is the coefficient of x and "c” is constant term.For more about coefficient make revision by clicking here. This is the first sub topic of this topic.
