Factoring Trinomials AC Method

When factoring a TRINOMIAL using the AC-B method, what goes on the bottom of the cross or diamond?

• What multiplies to AC

• What multiplies to B

• What adds to C

• What adds to B

What formula do we use to identify the "a", "b", and "c" when factoring?

• ax² +bx + c

• ax² +cx + b

• bx² +ax + c

• cx² +bx + a

To factor 3x² + 14x + 8, find the 2 clue numbers first. The clue numbers are:

• a⋅c =11 and b=14

• a⋅c =14 and b=3

• a⋅c =42 and b=8

• a⋅c =24 and b=14

• x+4

• x+3

• x+12

• x-3

• x-4

• 
• 
• 
• 

• x+4

• x+3

• x+12

• x-3

• x-4

To factor the trinomial 6x² + 11x +3, start by multiplying "a" times "c" and identifying "b".

• true

• false

• 9 and -2

• 9 and 2

• -9 and -2

• -9 and 2

What 2 numbers should go in the blanks instead of the "bx" term?

• The 2 numbers that multiply to 8 and add to -7, which are 8 and -1.

• The 2 numbers that multiply to -8 and add to -7, which are -8 and -1.

• The 2 numbers that multiply to -8 and add to -7, which are -8 and 1.

What should go in the final step?

• (4x + 1) ( x + 2)

• (4x - 1) ( x - 2)

• (4x + 1) ( x - 2)

• 4x (x-2) 1 (x-2)
