answer 1: # = color(red)(-7x^2 - 12x -11#
answer 2#=color(red)(29x^2) + color(blue)(22x) + 23#

Explanation:

There are two interpretations for the above question:

  • How much greater is #(11x^2 + 5x + 6) # than #(18x^2 + 17x + 17)#

Here we need to subtract:
#11x^2 + 5x + 6#
#color(red)(-)18x^2 color(red)(-) 17x color(red)(- )17#
# = color(red)(-7x^2 - 12x -11#

  • The second interpretation is to perform addition as the addition sign has been used in the question.

Grouping like terms:
#=color(red)((11x^2 + 18x^2)) + color(blue)((5x + 17x)) + (6 + 17)#
#=color(red)(29x^2) + color(blue)(22x) + 23#
