Solution:
Given that,
We have to simplify
[tex]w^2 + 7w^2 + 8w -5+9-2w^2[/tex]
We can simplify the above expression by combining the like terms
Like terms are terms that has same variable with same exponent and same or different coefficient
From given,
[tex]w^2 + 7w^2 + 8w -5+9-2w^2[/tex]
Group the like terms
[tex]w^2 + 7w^2 -2w^2 + 8w - 5+9\\\\Combine\ the\ like\ terms\\\\6w^2 +8w -5+9\\\\Combine\ the\ constants\\\\6w^2 +8w +4[/tex]
Thus the given expression is simplified
