Answer 1

To factor out the greatest common factor (GCF) from the expression \( -10x^5 - 15x^3 + 20x^2 \), we first determine the GCF of the coefficients and the variable parts.

1. **Coefficients**: The coefficients are -10, -15, and 20. The GCF of these numbers is 5.
2. **Variable part**: The variable with the smallest exponent is \(x^2\) (from \(20x^2\)). Therefore, the GCF for the variable part is \(x^2\).

Combining these two, the GCF of the entire expression is \(5x^2\).

Next, we factor out \(5x^2\) from each term:

\[
-10x^5 ÷ 5x^2 = -2x^3
\]

\[
-15x^3 ÷ 5x^2 = -3x
\]

\[
20x^2 ÷ 5x^2 = 4
\]

Putting these factored results together, we have:

\[
-10x^5 - 15x^3 + 20x^2 = 5x^2(-2x^3 - 3x + 4)
\]

Now looking at the answer choices provided, the correct answer is:

**Option:** \(5x^2(-2x^3 - 3x + 4)\)
