Question 856756
Note: you type p^2 to mean {{{p^2}}}. The ^ symbol is above the '6'



{{{144 - 9p^2}}}



{{{9(16 - p^2)}}} Factor out the GCF 9



{{{9(4^2 - p^2)}}} Rewrite 16 as {{{4^2}}}



{{{9(4 - p)(4 + p)}}} Use the <a href="http://www.regentsprep.org/regents/math/algebra/av6/Lfactps.htm">Difference Of Squares Rule</a> to factor



=========================================================================



So the full factorization is {{{9(4 - p)(4 + p)}}}
