Question

simplify
a. 12m2 - 9m + 5m - 4m2 - 7m + 10
b. p - (p - q) - q - (q - p)

Answer 1

Hi ,

a. 12m² - 8m + 5m - 4m² - 7m + 10

=( 12m² - 4m² ) + ( - 8m + 5m - 7m ) + 10

= 8m² - 10m + 10

b. p - ( p -q ) - q - ( q - p )

= p - p + q - q - q + p

= ( p - p + p ) + ( q - q - q )

= p + q

I hope this helps you.
