Question:
Simplify [tex]\left(s^{2}-2 s-9\right)+\left(2 s^{2}-6 s^{3}+s\right)[/tex]
Answer:
The solution is [tex]-6 s^{3}+3 s^{2}-s-9[/tex]
Explanation:
The expression is [tex]\left(s^{2}-2 s-9\right)+\left(2 s^{2}-6 s^{3}+s\right)[/tex]
Let us simplify the expression by removing the parentheses, [tex](a)=a[/tex]
Thus, the expression becomes,
[tex]s^{2}-2 s-9+2 s^{2}-6 s^{3}+s[/tex]
Let us group the like terms, we get,
[tex]-6 s^{3}+s^{2}+2 s^{2}-2 s+s-9[/tex]
Adding the similar terms, we have,
[tex]-6 s^{3}+3 s^{2}-s-9[/tex]
Thus, the solution of the expression [tex]\left(s^{2}-2 s-9\right)+\left(2 s^{2}-6 s^{3}+s\right)[/tex] is [tex]-6 s^{3}+3 s^{2}-s-9[/tex]
