Question

Factor completely the trinomial (if it is not factorable using integers, enter nf X^2 + 8x - 22

Answer 1

Not Factorable

Step-by-step explanation:

Given the trinomial:

`x^2+8x-22`

Following the normal factorization procedure, we multiply the first and the last term:

`-22* x^2=-22x^2`

However, from the factors of the product given below:

`\begin{gathered} -22x^2=-11x*2x \\ -22x^2=11x*-2x \end{gathered}`

There is none that sums up to the middle term 8x.

Thus, the trinomial is not factorable using integers.
