Answer:
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 :)
