Which is the expansion of a³ B³?
Question 1: What is the expanded form of a³ – b³? Answer: Expanded form of a³-b³ = (a-b) (a²+ab+b²).
How do you solve AB 3?
The formula is (a-b)³=a³-3a²b+3ab²-b³. You convert it to (a-b)³=a³-3ab(a-b)-b³ for an illustration. You take the drawing of the formula (a+b)³=a³+3a²b+3ab²+b³ from above and replace a by the difference a-b.
What are the rules of algebra signs?
For Multiplication and Division: If the signs are the same the result is positive. If the signs are different the result is negative. Addition: Note that the magnitude of a signed number is the same as its absolute value. When adding a positive number and a positive number: Add the magnitudes.
What is the purpose of algebra?
The purpose of Algebra is to make it easy to state a mathematical relationship and its equation by using letters of the alphabet or other symbols to represent entities as a form of shorthand. Algebra then allows you to substitute values in order to solve the equations for the unknown quantities.
