## Step 8 :

Pulling out lượt thích terms :8.1 Pull out lượt thích factors:-2k4 - 4k3 - 8k2=-2k2•(k2 + 2k + 4)

Trying to lớn factor by splitting the middle term

8.2Factoring k2 + 2k + 4 The first term is, k2 its coefficient is 1.The middle term is, +2k its coefficient is 2.The last term, "the constant", is +4Step-1 : Multiply the coefficient of the first term by the constant 1•4=4Step-2 : Find two factors of 4 whose sum equals the coefficient of the middle term, which is 2.

 -4 + -1 = -5 -2 + -2 = -4 -1 + -4 = -5 1 + 4 = 5 2 + 2 = 4 4 + 1 = 5

Observation : No two such factors can be found !! Conclusion : Trinomial can not be factored
