# How do you add #(2x^2 -11x) + (3x^2 + 11x - 4) #?

#### Explanation:

This looks confusing at first but I'll try to be as through as I can.

When I learned this, I was taught to drop the parentheses to make it easier.

You then put the variables from highest to lowest, as in the variable with the highest power to the smallest number next to the variable or number with no variable.

so the full answer is

Make sure to always put the variable with the highest power to the left. The variable with the lowest or no power, or number with no power, will go on the right.
