subtract 2x²-1 from 4x²+2
In order to solve the problem, first, we must write it as an algebraic expression,
[tex](4x^2+2)-(2x^2-1)[/tex]then, distribute the negative sign,
[tex]4x^2+2-2x^2+1[/tex]group terms that have the same literal part and the constant terms,
[tex](4x^2-2x^2)+(2+1)[/tex]simplify,
[tex]2x^2+3[/tex]Answer:
