Question

add the polynomials (9 x-6) + (-5x + 7)

Answer 1

Step-by-step explanation:

Simplify (2x + 5y) + (3x – 2y)

I'll clear the parentheses first. This is easy to do when adding, because there are no "minus" signs to take through any parentheticals. Then I'll group the like terms in accordance to their variables (keeping them in alphabetical order), and finally I'll simplify:

(2x + 5y) + (3x – 2y)

2x + 5y + 3x – 2y

2x + 3x + 5y – 2y

5x + 3y

These two terms are un-like (because they have different variables), so I cannot combine them. This means that I've gone as far as I can, so my hand-in answer is:

5x + 3y

5x+3y
