Question

Find the product.

3y²z(2y²z + 4yz - y + z)

Answer 1

Hello, so we are just going to distribute just like we did in the other one. Perhaps you are struggling with so many variables?

Answer 2

yeah

Answer 3

So we're going to take this easy.

Let's multiply 3y^2z with the first term 2y^2z.

So to attempt this, just work step by step. First multiply the numbers together, then the y's, and then the x's.

Answer 4

a) 4y^6z^2 + 13y^3z^12 - 3y^2z^2 - 3yz

b) 6y^4z^2 + 12y^3z^2 - 3y^3z + 3y^2z^2

c) 6y^2z^4 - 12y^2z^3 + 3y^4z^3 - 3y^2z^2

d) 3y4^z^2 + 3y3^z^2 - 6y^3z - 4
