    A variable is a symbol that we assign to an unknown value. It is usually represented by letters such asx, y, or t. For example, we might say that l stands for the length of a rectangle and w stands for thewidth of the rectangle. We use variables when we need to indicate how objects are related even though we may not know the exactvalues of the obje...

    An equation consists of two expressionsseparated by an equal sign. The expression on oneside of the equal sign has the same value as the expression on the other side. For Example: 4 + 6 = 5 × 2 l = 3 × w 3w + 4xy + 5 = 2w + 3

    A Quadratic Equation is an equation of the form: ax2+ bx + c = 0, where a, b and c are numbers and a ≠ 0 For Example: x2 + 2x + 3 = 0 2x2 + 5x – 7 = 0 2x2 + 5x = 8 (is a quadratic equation because it can be changed to 2x2) + 5x – 8 = 0 x2 + x = 0 (is a quadratic with c = 0) 2x2 – 7 = 0 (is a quadratic with b = 0) 2x + 3 = 0 (is not a quadratic beca...
