Factor Trinomial with Negative Second Term

Factor

8x²-56x+48

My first step is to

• AC!

• Factor out GCF

• Use SUM & DIFFERENCE

• USE SQ OF A BINOMIAL

9m²-12m+4

My factoring strategy is

• AC!

• GCF

• SUM & DIFFERENCE

• SQ OF A BINOMIAL

ax²+bx+c if b is negative and c is positive

• both factors are differences

  (x-_)(x-_)

• one factor is a difference and one is a sum

  (x+_)(x-_)

• both factors are sums

  (x+_)(x+_)

y²+10y+16

Factor this by

• finding a GCF

• grouping

• choosing factors of 16 that add to 10

• sum & difference pattern

Factor completely.
3x² - 9x -120

• 3(x - 8)(x + 5)

• 3(x + 8)(x - 5)

• (3x + 8)(x - 5)

• (3x - 8)(x + 5)

Factor the trinomial.

• 3(x+3)(x-2)

• 3(x-3)(x-2)

• (x+5)(x+1)

• 3(x-5)(x-1)
