Answer: =5x^2−8xy+y^2

if i could get brainliest that would be great

Step-by-step explanation:

2−3xy−5xy−7y2+4x2+8y2

=x2+−3xy+−5xy+−7y2+4x2+8y2

Combine Like Terms:

=x2+−3xy+−5xy+−7y2+4x2+8y2

=(x2+4x2)+(−3xy+−5xy)+(−7y2+8y2)

=5x2+−8xy+y2

Answer:

=5x2−8xy+y2

The simplification of the equation x² – 3xy – 5xy – 7y² + 4x² + 8y² is y² + 5x² - 8xy

Given:

x² – 3xy – 5xy – 7y² + 4x² + 8y²

collect like terms

x² + 4x² - 7y² + 8y² - 3xy - 5xy

5x² + y² - 8xy

Also written as

y² + 5x² - 8xy

Therefore, the simplification of the equation x² – 3xy – 5xy – 7y² + 4x² + 8y² is

y² + 5x² - 8xy
