Solve for K

k2 - 12k + 23 = 0

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
