2x + 1 -5x^2 - 2x + 3 (^2 is how to show squared with superscript)
-5x^2 +2x - 2x +3 +1 (reordered the terms)
-5x^2 +4 (combined like terms)
so its just
-5x^2 + 4

open the brackets first.. coz it is just addition of the two brackets...also, u should know that since t is addition u dont have to change the sign of the terms in the second bracket.
2x+1 -5x2 -2x +3.....it reads 5 x squared.
2x will get cancelled
1+ 5x2-2x +3
now add 1+3==4
5x2- 2x +4---5 x squared
thsi cud be the answer or
