Factor The Sum Or Difference Of Two Cubes Calculator – In algebra class, teachers often talk about the sum of two cubes and the difference of two cubes. The reason is that their structures are similar. The key is to “memorize” or remember the principles in this process.
The following procedure summarizes how to calculate the sum and difference of two cubes. Study them well.
Factor The Sum Or Difference Of Two Cubes Calculator
Rewrite the original problem as the sum of two cubes and simplify. Since this is the case of “and”, the binomial and trinomial elements will have positive and negative middle signs respectively.
Sum And Difference Of Perfect Cubes And Special Factoring
Apply the rule for the difference of two cubes and simplify. Since this is a “difference” expression, the next two factors in the trinomial will have negative and positive middle signs respectively.
At first glance, this question may seem “difficult.” However, if you stick to what we already know about the sum and difference of two cubes, we will be able to understand that this problem is easy.
Sometimes, the problem can not be solved by the combination or difference of two cubes. If you see a similar situation, try to eliminate the usual things. For numbers, the default is [latex]3[/latex], and for variables, the default is “[latex]xy[/latex]”. Therefore, the common factor will be their product, that is, [latex] left ( 3 right ) left ( right ) = 3xy [/latex].
When you break it down, you will see that we have a simple problem about the difference between two cubes.
