Question

Multiplying with Monomials 1) −7x^2(−3x^2 + xy + 5y^2)2) 3y(7x^2 − 2xy − 9y^2)

Answer 1

Given

The equation are given as

`\begin{gathered} -7x^2(-3x^2+xy+5y^2) \\ 3y(7x^2-2xy-9y^2) \end{gathered}`

Step-by-step explanation

1. The equation is given as

`-7x^2(-3x^2+xy+5y^2)=21x^4-7x^3y-35x^2y^2`

Answer

The answer is

`21x^4-7x^3y-35x^2y^2`

2. The equation is given as

`3y(7x^2-2xy-9y^2)=21yx^2-6xy^2-27y^3`

Answer

The answer is

`21yx^2-6xy^2-27y^3`
