    I will do 1 example for you.(3×2 − 2) + (2×2 − 6x + 3) = 5×2 + 1 – 6x First of all , you need to group them together3x2 + 2×2 = 5×2-2 + 3 = 1-6x Thus , this is your answer.For the rest of your question , it is the same. Group them together and you will get your answer. Don’t let Algebra fools you. It is just like normal math but only with 2x or 2x
