Factoring trinomials ac method

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

• What adds to B

• What multiplies to AC

• What multiplies to AB

• What adds to AC

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

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

• true

• false

To factor the trinomial  $6x^2+11x+3$   ...

• you need to find two numbers that multiply to 3 and add to 66

• you need to find two numbers that multiply to 18 and subtract to 11

•  you need to find two numbers that multiply to 18 and add to 11

• you need to find two numbers that multiply to 18 and add to 3

To factor the trinomial  $6x^2+11x+3$  , find 2 numbers that multiply to 18 and add to 11. Those two numbers are:

• 9 and -2

• 9 and 2

• -9 and -2

• -9 and 2

To factor the trinomial  $6x^2+11x+3$  ,  write the bx term, which is the 11x , using 2 terms like this:

•  $6x^2+9x+2x+3$  and then continue factoring by grouping

•  $6x^2-9x\ -2x+3$  and then continue factoring by grouping. 

•  $6x^2+10x+x+3$  and then continue factoring by grouping. 

•  $6x^2+9x-2x+3$  and then continue factoring by grouping. 

To factor 2x² +11x + 5, write the middle term using the 2 numbers that multiply to ___ and add to ___, make sure to include the "x". Write it like this:

*Choose 2 that apply.

• 10; 11; 2x² + 5x +2x + 5

• 22; 5; 2x² + 9x +2x + 5

• 10; 11; 2x² + 10x +x + 5

• 10; 11; 2x² + x +10x + 5

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.
