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

Co-efficient of is missing.

It should be 8.

Step-by-step explanation:

Given two polynomials:

1st polynomial:

2nd polynomial:

To find:

The value in the blank:

Solution:

Here, we have 3 pair of like terms.

2 terms with , 2 terms with and 2 terms with .

Like terms can be subtracted.

Subtracting the terms with , the coefficients will get subtracted.

Subtracting the terms with , the coefficients will get subtracted.

Subtracting the terms with , the coefficients will get subtracted.

Therefore, the answer is:

Co-efficient of is missing.

It should be 8.
