3x^2+16x^2+x+7-10x^2+22+15x-6x

Answer:
9x^2 + 10x + 29
Step-by-step explanation:
Let's sort the x^2, the x and the numbers without an x:
First, the x^2
3x^2 + 16x^2 - 10x^2
So that's 3 + 16 - 10 if we ignore the x^2.
We can simplify this to 9x^2, because 3+16-10=9.
The same for the x:
1x + 15x - 6x = 10x
And then there's the lone 7 and 22.
7 + 22 = 29
So to summarize:
9x^2 + 10x + 29
