Work Step by Step

We need to factor: $x^2-26x+153$ The first term in each binomial must be $x$, since $x^2$ has no coefficient. The operation in each binomial is subtraction since the last term in the trinomial is positive and the second is negative. Since $-9-17=-26$ and $(-9)(-17)=153$, the other two terms are $ -9$ and $-17$. Thus, we have: $x^2-26x+153=(x-9)(x-17)$
