Multiply Multiple Binomials

Where is the error in the following problem if it is solved with the distributive property?



• multiplied incorrectly

• Forgot to multiply the inner terms

• combined like terms incorrectly

• The first term should not be squared

Using all three methods, the last step is always to...

FOIL, Distributive, Box Method

• Multiply all the terms together

• Combine like terms

• Simplify

• Subtract the largest term

Use any method to multiply the following binomials.

(3p-7)(2p-2)

• 6p^2 -20p - 14

• 5p^2 - 20p + 14

• 6p^2 -6p - 14p + 14

• 6p^2 -20p + 14

What term should go in the blue box?



• 21x^2

• 21x

• 10x^2

• 10x

This is an example of multiplying binomials with what type of method?



• Box Method

• Addition Method

• Foil Method

• Distributive Method

What does the O in FOIL stand for?



• opposite

• outside

• over

• oval

Using the Box method what is the first step to solving the following problem?

(2x+4)(x-3)

• Wrote x -3 on the left side of the box

• To multiply 2x by x

• To multiply 4 by x

• Write 2x + 4 on the top of the box

Use any method to multiply the following binomials.

(3x-7)(x-2)

• 3x^2 -13x + 14

• 3x^2 -13x - 14

• 3x^2 -6x -7x + 14

• 3x^2 -1x + 14

Using the FOIL method the first step would be to multiply x by 4x.

• True, always multiple the variables first

• True, this is always the first term in FOIL

• False, the first step is 5 times 4x

• False, the first step is 5 times -2

Using the FOIL method the first step is to multiply 2x by x, what is the last step?

(2x+4)(x-3)

• To multiply 2x by -3

• To multiply 2x by x

• To multiply 4 by x

• To multiply 4 by -3
