Which type of factoring would you use first? \(2x^2-7x-4\)

• GCF

• D.O.T.S.

• Trinomial a=1

  ( x )( x )

• Box Method

Which type of factoring would you use first? \(3x^2-11x+6\)

• GCF

• D.O.T.S.

• Trinomial a=1

  ( x )( x )

• Box Method

Select which monomial belongs in the last box:

• 1

• 4x

• -16

• 6

Answer explanation

The correct choice is -16 because a monomial is a single term with a coefficient and variable. -16 fits this definition as it is a constant term without a variable.

What is the GCF of the highlighted row:

• 2x

• x

• 6

• 3

Answer explanation

The GCF of the highlighted row is 3 because it is the greatest common factor of the numbers in the row.
