SIMPLIFY AND PUT IN ORDER FOR BRAINLIEST y= 46x -87x^3 +23x^2 -31x^6 +12 -23x^2

y = -31x^6 - 87^3 +46x +12

Step-by-step explanation:

Place the numbers with the highest degree first (-31 x ^ 6) and go in order until you reach the number with the lowest degree (12). When you do that, you get:

y = - 31x^6 - 87x^3 + 23x^2 - 23x^2 + 46x +12

As you can see, the numbers based on the amount of their exponent were placed in order, no matter what the coefficient is. But, there are two numbers with ^2, so we have to cancel them out. In order to do that, you have to add/ subtract the two numbers with the same exponent.

23x^2 - 23x^2 = 0

Since the answer is 0, we canceled both of the numbers out, so the final polynomial in its standard form is:

y = -31x^6 - 87^3 +46x +12

Hope this helps :)
