Answer:
The equivalent expression to the given expression is:
[tex]6p^2r(5p^2q^3+7-3q^2)[/tex]
Step-by-step explanation:
We are given an algebraic expression consisting of 3 terms as:
[tex]30p^4q^3r+42p^2r-18p^2q^2r[/tex]
As we could see that each of the terms of the expression has a common factor as: [tex]6p^2r[/tex]
Hence, we take out common the common factor and write the remaining terms inside the bracket.
We will get our expression as:
[tex]6p^2r(5p^2q^3+7-3q^2)[/tex]
