Part 1 presents mathematical formulas together with other material, such as definitions, theorems, graphs, diagrams, etc., essential for proper understanding and application of the formulas.
A cubic equation has the form. ax3 + bx2 + cx + d = 0. where a 6= 0. All cubic equations have either one real root, or three real roots. In this unit we explore why this is so. Then we look at how cubic equations can be solved by spotting factors and using a method called synthetic division.

nice canonical form for the cubic formula that is relatively easy to remember. We show how to verify that the formula is correct, and we identify when it is profitable to use it.
Cubes 1 to 20 is the list of cubes of all numbers from 1 to 20. The values of cubes from 1 to 20 range from 1 to 8000. Memorizing these values will help students to simplify the time-consuming equations quickly. The cube 1 to 20 in the exponential form is expressed as (x) 3. Cube 1 to 20: Exponent form: (x) 3; Highest Value: 20 3 = 8000; Lowest ...
