Samuel found the difference of the polynomials. (15x² + 11y² + 8x) - (7x² + 5y² + 2x) = ?x² - 6y² + 6x. What value is missing from his solution?

Solution:

The terms of polynomials are defined as the parts of the expression that are separated by the operators "+" or "-".

Like terms in polynomials are those terms which have the same variable and same power.

Terms that have different variables and different powers are known as unlike terms. 

Given, the equation

(15x² + 11y² + 8x) - (7x² + 5y² + 2x) = ?x² - 6y² + 6x

We need to find the coefficient of x².

By multiplying the negative sign inside the brackets

15x² - 7x² + 11y² - 5y² + 8x - 2x = ?x² - 6y² - 6x

On further simplification

8x² + 6y² + 6x = ?x² - 6y² - 6x

Therefore, the value missing is a term like 8x². The missing value is coefficient 8.

Samuel found the difference of the polynomials. (15x² + 11y² + 8x) - (7x² + 5y² + 2x) = ?x² - 6y² + 6x. What value is missing from his solution?

Summary:

Samuel found the difference of the polynomials. (15x² + 11y² + 8x) - (7x² + 5y² + 2x) = ?x² - 6y² + 6x.The missing value is coefficient 8.
