Simplify the following expression.
3x4 +2x - 5x2 + 4x2 +6x-2x-3x4 + 7x - 3x3

Hi! Alrighty this is a long one so here we go:

You first are going to want to find the like terms then add or subtract those together

3x^4 + 2x - 5x^2 + 4x^2 + 6x - 2x - 3x^4 + 7x - 3x^3

I made the like terms look like eachother if that makes any sense^

So subtract 3x^4 from 3x^4, which just cancels eachother out

2x - 5x^2 + 4x^2 + 6x - 2x + 7x - 3x^3

Now do the next ones which are the ones in bold (it doesnt matter which ones you do but these are the ones im doing)

So if you add those together, you now have

2x - 1x^2 + 6x - 2x + 7x - 3x^3

Add/subtract the bold ones again

13x - 1x^2 - 3x^3 is your answer!

Hope I helped have a good day :)

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
