Work Step by Step

We subtract the $x^5$-terms as follows $$ 12x^5-4x^5=8x^5 $$ then subtract the $x^4$-terms as follows $$ -13x^4-5x^4=-18x^4 $$ then subtract the $x^2$-terms as follows $$ 7x^2-2x^2=5x^2 $$ then subtract the constant terms as follows $$ 0+1=1 $$ Hence the result is $$8x^5-18x^4+5x^2+1.$$
