Question

Simplify the expression: w2 + 7w2 + 8w - 5 + 9 - 2w2

Answer 1

`6w^2 +8w +4` is the simplified expression

Solution:

Given that,

We have to simplify

`w^2 + 7w^2 + 8w -5+9-2w^2`

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,

`w^2 + 7w^2 + 8w -5+9-2w^2`

Group the like terms

`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`

Thus the given expression is simplified
