Answer 2

$\underline{\Large\mathbf{Question}}$

Add 4p² - 4pq + 7r² and - 6p² + 10pq + 8r²

$\underline{\underline{\huge\mathfrak{Solution}}}$

( 4p² - 4pq + 7r² ) + ( - 6p² + 10pq + 8r²)

= 4p² - 4pq + 7r² - 6p² + 10pq + 8r²

Writing like terms together :

= 4p² - 6p² + 7r² + 8r² - 4pq + 10pq

= -2p² + 15r² + 6pq

Hope this helps! ;)
