Find the sum of 2x 2 + 3x - 4, 8 - 3x, and - 5x 2 + 2. - 3x2 - 2 - 7x2 - 2 - 3x2 + 6 - 7x2 - 6x - 2

2x 2+3x - 4, 8-3x, - 5x 2 + 2

Im guessing that 2x (2) ?

(4x+3x-4) + (8-3x) + (-10x+2)

7x-4+8-3x-10x+2

Add all x's

14x

Add all the integers.

6

So, 14x + 6.

What is the second line?

-3x (2) - 2-7x (2) - 2-3x (2) + 6-7x (2) - 6x-2

So ... - 6x-2-14x-2-6x-2-14x-6x-2

-6 is the integer.

-46x is the variables.

-46x-6
