For this case we must simplify the following expression:
[tex](2a ^ 3-5a) - (7a+ 3a ^ 2) =[/tex]
By definition of the law of multiplication signs we have to:
[tex]- * + = -[/tex]
Rewriting the expression we have:
[tex]2a ^ 3-5a-7a-3a ^ 2 =[/tex]
We add similar terms taking into account that:
Equal signs are added and the same sign is placed.
[tex]2a ^ 3-3a ^ 2-12a[/tex]
ANswer:
[tex]2a ^ 3-3a ^ 2-12a[/tex]
