Answer:
Step-by-step explanation:
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring k2-12k+23
The first term is, k2 its coefficient is 1 .
The middle term is, -12k its coefficient is -12 .
The last term, "the constant", is +23
Step-1 : Multiply the coefficient of the first term by the constant 1 • 23 = 23
Step-2 : Find two factors of 23 whose sum equals the coefficient of the middle term, which is -12 .
-23 + -1 = -24
-1 + -23 = -24
1 + 23 = 24
23 + 1 = 24
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
