Factoring with a NOT equal to 1

• positive 60
• positive 19
• positive
• negative 19
• negative 60
• negative

Answer explanation

Remember, if ac is positive, the factors must match b

• 1 and 60

• 2 and 30

• 3 and 20

• 4 and 15

• 5 and 12

Answer explanation

a=5, c=12 so you are looking for the factors of +60

b=+19 so which of the factors listed ADD t 19?

Answer explanation

If you are using the box, remember to divide out the GCF

If you are using double ( )( ),

remember you have an extra factor of 5

If you are using grouping, one of the factors must be identical.

• -4/5

• 4/5

• -3

• 5/4

• 3

Answer explanation

Remember, when you set them = 0 and get rid of the + or -, you must add the opposite and divide by the coefficient.

• positive 12
• negative 8
• negative
• negative 12
• positive 8
• positive

Answer explanation

Remember, if ac is positive, the factors must match b

What factors of ac will "sum" up to b?

 $3x^2-8x+4=0$

• -1 and -12

• -2 and -6

• -3 and -4

Answer explanation

a times c is 12,so of all the factors of 12, -2 and -6 are the only ones that add up to -12

Answer explanation

If you are using the box, remember to divide out the GCF

If you are using double ( )( ),

remember you have an extra factor of 5

If you are using grouping, one of the factors must be identical.

• 2/3

• -2/3

• 2

• 3/2

• -2

Answer explanation

Remember, when you set them = 0 and get rid of the + or -, you must add the opposite and divide by the coefficient.

• 5

• 3

• 6

Answer explanation

You have to go to the SMALLEST of the a,b and c and check all the factors of the smallest one

• negative 10
• negative 9
• one negative and one positive
• negative
• positive 10
• positive 9
• positive

Answer explanation

Remember, if ac is positive, the factors must match b
