What is the sum of the given polynomials in standard form? (x^2 – 3x) + (–2x^2 + 5x – 3)

Step-by-step explanation:

(x^2 – 3x) + (–2x^2 + 5x – 3)

To get the sum of these two polynomials, remove the brackets and arrange the like terms together:

x^2 - 3x - 2x^2 + 5x - 3

x^2 - 2x^2 + 5x - 3x - 3

Now sum up the like terms to get:

-x^2 + 2x - 3

If you do not want to write x^2 in negative form, you can take '-' as a common, change the signs inside the brackets accordingly and instead write it as:

- (x^2 - 2x + 3)

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.
