Question

multiply 3x (2x - 1) by following these steps:
step 1: drag tiles to the section labeled factor 1 to represent the factor 3x.

Explanation:

Step1: Represent 3x with tiles

Drag three $+x$ tiles to the Factor 1 section.

Step2: Apply distributive property

Multiply $3x$ by each term in $(2x-1)$:
First term: $3x \times 2x = 6x^2$
Second term: $3x \times (-1) = -3x$

Step3: Combine results

Add the two products together.

Answer:

$6x^2 - 3x$
