#### Explanation:

Begin by writing the expression without the brackets. Since there is no numeric value written outside the bracket we can assume there is a 1.

That is

#1(4x^2-11x+10)+1(5x-31)# Hence

#to4x^2-11x+10+5x-31# now

#color(blue)"collect like terms"#

#color(red)(4x^2)color(magenta)(-11x+5x)color(blue)(+10-31)=4x^2-6x-21#
