Question 1048308

{{{p(c) = c^2 + c}}}

 complete the following.
(a) Evaluate 
{{{p(-4)}}}
 
{{{p(-4)= (-4)^2 + (-4)}}}

{{{p(-4)= 16 -4}}}

{{{p(-4)= 12}}}


(b) Solve 
{{{p(c) = 2}}}

{{{2= c^2 + c}}}

{{{0= c^2 + c-2}}}

{{{c^2 + c-2=0}}}........factor completely, write {{{c}}} as {{{2c-c}}}

{{{c^2 + 2c-c-2=0}}}

{{{(c^2 + 2c)-(c+2)=0}}}

{{{c(c + 2)-(c+2)=0}}}

{{{(c-1)(c+2)=0}}}

solutions:

if {{{(c-1)=0}}}->{{{c=1}}}
if {{{(c+2)=0}}}->{{{c=-2}}}
 
answers: {{{-2}}},{{{1}}}
