Question

To factor the expression 3x2 – 9x, Caleb found the GCF as shown.   List the factors: 3x2 = 3 • x • x 9x = 3 • 3 • x GCF = 3 • 3 • x • x = 9x2 what is calebs error?

Answer 1

$3x^2=\boxed{3}\cdot\boxed{x}\cdot x\\9x=\boxed{3}\cdot3\cdot\boxed{x}\\\\GCF(3x^2,\ 9x)=\boxed{3}\cdot\boxed{x}=3x$

Answer 2

Answer:

Step-by-step explanation:

caleb found the product of all factors not just the ones common to each term.
