I tried this, but what happens to 3w on both sides?

Use FOIL to find each product

(5y^3w^2+z)(2y^3w^2+3z)

What’s FOIL?

At any rate, the “3” is the exponent of the variable “y”. It is not to the multiplied by “w”.

For clarity, you may space the terms this way:

(5y^3 w^2 + z)(2y^3 w^2 + 3z)

Better? Now multiply the terms. You’ll get

10y^6 w^4 + 17y^3 w^2 z + 3z^2
