Answer:
[tex]-x^{2}+4x[/tex]
Step-by-step explanation:
we have
[tex](x^{2}+x)-(2x^{2} -3x)[/tex]
step 1
Eliminate the parenthesis
[tex]x^{2}+x-2x^{2} +3x[/tex]
The symbol of the term 3x is incorrect, must be positive instead of negative
so
[tex]-(-3x)=+3x[/tex]
Group terms that contain the same variable
[tex](x^{2}-2x^{2})+(x+3x)[/tex]
Combine like terms
[tex]-x^{2}+4x[/tex]
