What is the standard form of y^2+6y+9+4y^4

The standard form of y^2+6y+9+4y^4 is 4y^4 + y^2 + 6y + 9.

To find the standard form of the expression y^2 + 6y + 9 + 4y^4, we need to collect like terms and arrange them in descending order of the variable's exponent.

Starting with the given expression:
y^2 + 6y + 9 + 4y^4

We first combine the like terms y^2 and 4y^4:
4y^4 + y^2 + 6y + 9

Now, we reorder the terms in descending order of the variable's exponent:
4y^4 + y^2 + 6y + 9

So, the standard form of the expression y^2 + 6y + 9 + 4y^4 is 4y^4 + y^2 + 6y + 9.
