I guess I'll solve
OpenStudy (anonymous):
Ok so to solve you need to put it in order so I put it as z^2 +18z +45
OpenStudy (anonymous):
Since 18z and 45 are both positive you will get
OpenStudy (anonymous):
(x+5)(x+9)
OpenStudy (anonymous):
Wait

\[18z+45+z^{2}\]
first we put like term z one side
\[18z+z^{2}+45\]
combine like terms by adding coefficient and adding power
=\[19z^{3}+45\]

Can you help me solve this problem? What are the ordered pair on a graph for the absolute value of f(x)=|x-1|+2 ?
