Solution Steps
To solve the first question, we need to factor the expression \(3p^5 - 12p^3\). We can start by identifying the greatest common factor (GCF) of the terms, which is \(3p^3\). Factoring out the GCF will help us determine the other factor.
For the second question, we need to factor the expression \(50a^2b^5 - 35a^4b^3 + 5a^3b^4\) completely. We should first find the GCF of all the terms, which is \(5a^2b^3\), and then factor it out to simplify the expression.
Step 1: Factor the Expression \(3p^5 - 12p^3\)
To factor the expression \(3p^5 - 12p^3\), we first identify the greatest common factor (GCF) of the terms, which is \(3p^3\). Factoring out the GCF, we have:
\[
3p^5 - 12p^3 = 3p^3(p^2 - 4)
\]
The expression \(p^2 - 4\) is a difference of squares, which can be further factored as:
\[
p^2 - 4 = (p - 2)(p + 2)
\]
Thus, the completely factored form of the expression is:
\[
3p^5 - 12p^3 = 3p^3(p - 2)(p + 2)
\]
Step 2: Factor the Expression \(50a^2b^5 - 35a^4b^3 + 5a^3b^4\)
For the expression \(50a^2b^5 - 35a^4b^3 + 5a^3b^4\), we first find the GCF of all the terms, which is \(5a^2b^3\). Factoring out the GCF, we have:
