3x^2+8x+7x
3x^2+15x
Find the degree of –5w^3-4w^2+7w+16
The degree of a polynomial is the highest exponent of its variable.
In this case, the highest exponent of the variable w is 3. Therefore, the degree of the polynomial -5w^3-4w^2+7w+16 is 3.
To simplify the expression 3x^2 + 8x + 7x, you need to combine like terms.
First, let's group the terms that have the same variable, which is x in this case.
The given expression can be rewritten as:
3x^2 + (8x + 7x)
Now, let's combine the x terms:
3x^2 + 15x
So, the simplified form of the expression 3x^2 + 8x + 7x is 3x^2 + 15x.
