Answer:
\(-28p^5-21p^4+7p^3\)
Step-by-step explanation:
\(-7p^3(4p^2 + 3p - 1)\)
To find the product apply oprder of operations PEMDAS and properties of exponents
\(a^m \cdot a^n= a^{m+n}\)
\(\frac{a^m}{a^n} =a^{m-n}\)
Multiply -7p^3 inside the parenthesis
\(-7p^3(4p^2 + 3p - 1)\)
\(-28p^5-21p^4+7p^3\)
