How can you use the distributive property to check your work when factoring?

The Distributive property applies multiplication to an existing addition statement. It means that a number outside the parentheses/brackets of an addition problem can be multiplied by each number inside the parentheses/brackets.

For example:

Let us consider factorization of

1. 10m + 25

It becomes 5(2m + 5)

2. 27m² + 18m

it becomes 9m(3m + 2)

So, in order to check if we are factorizing in the correct steps, we shall multiply the split factors and the answer should be the same as the factor that needed to be factorized. We will multiply (9m * 3m) +(9m *2) = 27m²+18m

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
