$(15 p - 11) (p - 1)$ $(15p-11)(p-1)$

Explanation:

Use the criss-cross method of factoring,

$1 X X X X X X - 1$ $1color(white)(XXXXXX)-1$

$15 X X X X X - 11$ $15color(white)(XXXXX)-11$

$- 11 - 15 = - 26$ $-11-15=-26$ $\Leftarrow$ $lArr$ this is our b-value in the equation $15 p^{2} - 26 p + 11$ $15p^2-26p+11$ thus, we criss-crossed correctly.

$:.$ $(15p-11)(p-1)$
