samuel found the difference of the polynomials.\n$(15x^{2}+11y^{2}+8x)-(7x^{2}+5y^{2}+2x)=\\square x^{2}+6y^{2}+6x$\nwhat value is missing from his solution?

samuel found the difference of the polynomials.\n$(15x^{2}+11y^{2}+8x)-(7x^{2}+5y^{2}+2x)=\\square x^{2}+6y^{2}+6x$\nwhat value is missing from his solution?

Answer

Explanation:

Step1: Remove parentheses

$$(15x^{2}+11y^{2}+8x)-(7x^{2}+5y^{2}+2x)=15x^{2}+11y^{2}+8x - 7x^{2}-5y^{2}-2x$$

Step2: Combine like - terms

For the (x^{2}) terms: (15x^{2}-7x^{2}=(15 - 7)x^{2}=8x^{2}) For the (y^{2}) terms: (11y^{2}-5y^{2}=(11 - 5)y^{2}=6y^{2}) For the (x) terms: (8x-2x=(8 - 2)x = 6x)

Answer:

(8)
