Question

-10x² + 70x

Explanation:

Step1: Identify greatest common factor

The terms $-10x^2$ and $70x$ share a common factor of $-10x$.

Step2: Factor out the GCF

Divide each term by $-10x$ and write the expression as a product.

$$\begin{align*} -10x^2 + 70x &= -10x \cdot x + (-10x) \cdot (-7) \\ &= -10x(x - 7) \end{align*}$$

Answer:

$-10x(x - 7)$
