Foil Method Binomials

In the following question, which terns need to be combined in order to simplify correctly.



• 9x^2 and 49

• -21x and -21x

• -21x and 9x^2

• -21x and 49

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

(x + 2)(x - 9)

• x² + 7x - 18

• x² - 7x - 18

• x² - 11x - 18

• x² - 18x - 7

Multiply:
(3x – 1)(x + 5) 

• 3x² + 4x + 5

• 3x² + 4x - 5

• 3x² + 14x + 5

• 3x² + 14x - 5

Whether multiplying binomials using FOIL or using a BOX, I must remember to _________ like terms from the middle two terms.

• combine

• walk

• multiply

• call

Multiply:

(3x – 1)(x + 5)

• 3x² + 4x + 5

• 3x² + 4x - 5

• 3x² + 14x - 5

Multiply:

(3x + 2)(2x + 4)

• 6x² + 16x + 8

• 5x² +11x + 6

• 5x² + 16x + 6

What does the F in FOIL stand for?

• Fire

• First

• Friends

• Frappachino

Which method do you prefer to multiply binomials?
