#32x^2#
just add the coefficients of the same order

#(23x^2-27)-(-31x^2-41) -(22x^2+14)#

#23x^2-27 +31x^2+41-22x^2-14#

#23x^2+31x^2-22x^2-27+41-14#

#(23+31-22)x^2 -27+41-14#

#32x^2+14-14#

= #32x^2#

#32x^2#

We can distribute the negatives to now obtain the expression

#23x^2-27+31x^2+41-22x^2-14#

Now, we just combine the terms with the same degree with each other. We get

#32x^2-27+41-14#

The constants cancel out, and we're left with

#32x^2#

Hope this helps!
