Question

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

simplify the expression by combining like terms. write the terms from the highest to the lowest power of the varible

Answer 1

9x^2 + 10x + 29

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
