Answer:
The simplified form is
[tex]-3a^3+5a^2-3a+7[/tex]
Step-by-step explanation:
Given the expression
[tex](a^3-2a+5)-(4a^3-5a^2+a-2)[/tex]
we have to simplify the above expression.
[tex](a^3-2a+5)-(4a^3-5a^2+a-2)[/tex]
Step 1: Opening the brackets
[tex]a^3-2a+5-4a^3+5a^2-a+2[/tex]
Step 2: Combining like terms
[tex](a^3-4a^3)+5a^2-(2a+a)+(5+2)[/tex]
[tex]-3a^3+5a^2-3a+7[/tex]
which is required simplified form
