To make things easier, you can take the factor $- 1$ $-1$ out:

$= - 1 \cdot (x^{2} - 11 x - 26)$ $=-1*(x^2-11x-26)$

Now we factor $- 26 = - 13 \cdot 2$ $-26=-13*2$

These factors add up to $- 11 =$ $-11=$ goal accomplished!

Complete factoring:

$= - (x - 13) (x + 2)$ $=-(x-13)(x+2)$

We can even make the $-$ $-$ disappear:

$= (13 - x) (x + 2)$ $=(13-x)(x+2)$

How do you factor −x2+11x+26-x^2 + 11x + 26?
